I really love Etsy, i find it much better that eBay for unique items and high quality goods, also the amount of people who sell tailored goods is a great plus.
As a seller on Etsy i also find it much more attarctive to have my business here, i get a lot of dedicated customers who look for high quality handmade goods.
Billing is simple and fees are lower than eBay. listing is easy, but sadly combined shipping is a bit of a nightmare, if that was more customisable then it would be the best selling platform out there in my opinion.... Still is my favourite though.
