We have some Fab news from online selling platform, Coriandr.com. They have just introduced Seedlings which is very similar to Etsy Mini. I personally think it's even better as it allows the same row and column input but it's not static, when you refresh the page it actually rotates your products randomly so visitors will never be bored. If you are a seller already on Coriandr.com then try try Seedlings for yourself.
If you are not yet selling on Coriandr.com then it might be worth checking them out as they offer forever listings, that's right, pay your fee once and that's it until your item is sold.
