Ok, here we go! You ask a lot of questions, it's going to be long. 
STORE FRONT END
First impression, the site looks professional and makes me confident as a buyer that it?s a legitimate company. The light and dark contrast stands out nicely and makes the text easy to read. The mini Logo visible on the bookmark is nice too; simple but effective.
I didn?t like the way the brands kept rearranging themselves on the front page, it just made me feel lost when I kept going back to look in each area. Also, if I chose how to sort the products on each brand page, that choice did not sustain when I moved to another brand. It would have been nice to have that option remembered.
I also missed a ?Search? option, to type in whatever I might be looking for. Be it Rugs or Baby Clothes or Chairs, which sometimes spanned multiple companies, some of which I?d never heard of.
ORDERING
The issues with the code are already known about. One thing I noticed and was immensely annoyed by is that there was no way to preserve my basket while I was querying the problem with paying. This meant I had to go and re-add all my products every half hour while trying to get the code issue resolved!
I can see why you don?t want people to have things in their basket all day, but would there be some way you could click a ?Help!? button which would freeze your account for a few hours at least, to maintain your order while having an issue dealt with? Or a 24 hour help phone line/web chat, with someone who can hold the order if you have a legitimate issue that needs resolving.
When I was making my purchase, the screen went complete to the dark honeycomb effect just after I clicked to confirm. I don?t know if there was meant to be a popup that my blocker stopped? Randomly clicking on the honeycomb made it vanish and go to a confirmation page, but it was a bit disconcerting to be faced with a dark page of nothing just after paying!
Delivery is slow if you?re used to the next day delivery of a lot of website, but given the business model your operating on I can see why it?s slower. I personally don?t mind too much in this instance, but it might make me wary about ordering something to a tight deadline ? for example a birthday present.
MY ACCOUNT
The My Account area is nicely laid out, the options are clear. However going into my Order History is currently a bit confusing... The order is appearing three times with the same ID, the first marked with a voucher code and then two more saying refunded. What does that mean? I?m pretty sure I?ve not been refunded twice! Surely it?d be clearer just to have one order code listed, then more details when you click into it.
I also note that since the money was refunded (within 24 hours in my case ? thanks!) my order doesn?t tell me estimated delivery times anymore. I think it did beforehand? But this was a week or so ago for me, I could be remembering wrong. It would be helpful to display the delivery times.
Going through to the Contact Us page, I expected to be presented with an address and telephone number, maybe a comments box. I wasn?t expecting a helpdesk setup, and it?s a bit jarring that it doesn?t quite match up with the main part of the site. That does reduce the professional feel quite significantly.
To be honest, the lack of address and telephone number sets of warning bells in my mind. If you?re a reputable company, why hide your contact information? I wouldn?t really be happy if I had to wade through Companies House to get it. Even if it?s an 0845 number and PO Box address, at least having something on the site would be an improvement.
I did like the section in the FAQ about how to pronounce Achica. My DH and I were puzzling over that one for a while before I stumbled across it!
The Delivery Status screen is only helpful if the companies whose products you?ve gone for are on there. As it happens, mine aren?t and their absence is slightly worrying. Even if they were there with a TBC I?d feel happier!
EMAILS / BLOG
I received these for a week or so, but to be honest one a day was too much for me ? I ended up just deleting them without reading and I?ve now stopped them. A week in advance would be much better, saying all the exciting things that were coming up over the next week. Possibly with a link through to log any that sound interesting so a further reminder email could be sent?
In addition, I?d also really like an option where I could make a note of a keyword of something I was interested in getting now or in the future. For example a Garden Parasol, which there have been a few different companies providing recently. An email could be sent out each time a company comes up with a product matching those keywords, drawing me back to the site to go see without bombarding me.
If you were really savvy, you could even get the tech bods to print out a report of all the keywords people have saved as something they?re interested in. Then that gives you a good idea of what things people want to see on the site!
I admit I haven?t actually gone to look at the blog and only glanced at the Facebook site. I?ll endeavour to go and take a look if I get some time next week.
PRODUCTS
The products on the whole were good. Some I was interested in, some I wasn?t, but there seemed to be a good mix. I also learnt about some new brands I?d never heard of before that seem quite cool, so thanks for that!
One glaring omission though is the lack of any electrical products. Where?s Nintendo, Sony, LG, Samsung, etc? White goods, audio/visual, mobile phones, etc?
The offers were a mixed bag really. Some were quite good, some not so good. There seem to be good savings to be made if you?re choosy about what you go for.
One thing I noticed earlier is that some of the delivery dates of products seem to be set to a previous run through? There are ?Delivery in May? dates on Lifemarque in particular... That seems a bit sloppy and potentially confusing/off-putting.
Also, it?s really inconvenient to have all the new products appear at 7am in the morning. I?m commuting to work at that point, and a few times I noticed really popular products had already gone by the time I could get to a PC. If it were my DH, he wouldn?t get to them until after work in the evening!
It might be better to either move to the time earlier to enable logging on before work, or to stagger the brands releasing throughout the day to give people better chance of grabbing the product they want?
CONCLUSION
I?m waiting to see how delivery works, considering I work full time and tend to get irrationally annoyed by being carded by couriers the other side of the county that want three forms of ID and a blood sacrifice before they?ll relinquish a parcel. Hopefully the couriers you?re working with are good ones! Tracking information on the website would be appreciated too. I?ll report back once I get to this stage.
I might well use the site again. I?ve been keeping a curious eye over it and seen a few things I?m after. It?d be nice to mark them for future consideration if they came through the cycle again, since right now I?m not in a position to splash out but might be in a few months time.
Letting people mark items would also let you know good things to keep offering! It could even work on things that are Out of Stock, if you could say "But I wanted one!" and get an email sent out next time it comes on offer.
I?ll probably take a more determined look in about October time (given the slow delivery) and see about getting some bits and pieces for Christmas presents. So if you?re going to market Christmas items, you might want to start then!
As for recommending to others, that depends at least partially on the delivery and products!
Hope that?s helpful! :) Let me know if there?s any other areas you?d like me to look over.
