I am sick of this whole "google me if you want to look at my store".
Its not putting up a link to your store, no, but it IS still advertising and quite frankly its f*cking rude.
There is an advertising section - £30 for 3 months. £10 a month. 33p a day.
Pay to advertise, or don't mention that you sell x,y & z. If you want MN for customers, then you should pay for them and then you can mention your store in any conversation you like, link to your ad, whatever.
If you don't want to pay, then just chat about whatever is your chosen subject be it craft stuff, pushchairs, clothes, nappies whatever.
Have namechanged because I don't want to directly piss off people, but DO want to rant where it can be seen (if that makes any sense whatsoever).
