"Unlike Shopify, there aren’t any bandwidth or storage limits, not even a setup fee; it’s just a simple way to sell your wares online"...."The premium version in a nutshell, allows you to post and sell up to 50 products at a time (10 in free)"
Saying there's no limits of one specific type, followed by another type of limit (a prohibitively small limit at that) seems a little disingenuous.
They need a better value prop than unlimited bandwidth or storage limits - those are near the bottom of the list of importance for a small-time eCommerce site.
