So I was very late to the Vinted party as a seller and decided that if posting became a faff, as you don't make much per item I'd jack it in. I almost forked out on a small printer for this just to do my labels.
It actually worked out well. Pricing wise although I want to get rid of stuff I'll try still to get the best price I can ... when you upload an item it gives you prices for similar items in the same condition category and i tend to start just under the top so. Can drop if I need to.
Buyers will often make an offer and provided they aren't being daft I'll accept/. If they are a bit lower I'll counter by meeting at a mid point. I find most stuff goes quite quickly.
I do take time to take lots of decent pictures in good light and I'm completely transparent about flaws. I've only done about 70 sales but they are all 5* and until recently with a nice paragraph of good feedback which really makes me buzz! I'll often pop freebies in a parcel too such as beauty samples I won't use or an extra similar item if it's kids stuff.
I have a box under the bed with my stuff to sell stored in and once it's full but I've other stuff I want to list I'll either massively drop prices of what's already on there or charity an item. My rule is I must always be able to put the lid on properly!
I only use shipping methods that are convenient for me (Yodel as I go past a few drop off points most days). I also recycle all packaging we get before buying stuff especially for Vinted parcels.
It's possible to make more than a few quid per item. I draw my £ out as soon as it's paid, put it in a separate savings pot then use it to buy vouchers for my M & S Christmas good shop.
I'm definitely happy with the money I've made vs the time and effort it takes.
