I must say that the first thing I think of when seeing your domain is "Shoplifting"; which isn't good.<p>Landing page is way too uninformative (especially the visible-portion). I don't really have a good idea what this does exactly (and I still don't after reading).<p>Is it basically bookmarking product pages? I sort of understand the pain-point you're trying to solve with this. I'm just not sure that people will want to sign-up with a service to organize things they may want to buy; I could be wrong.<p>I'd recommend having the page just open to the app itself, rather than an image and a login. Let me use it then tell me to create an account to save.
It wasn't simple after you wanted me to log in with a social networking credential. In fact it made our relationship quite complicated. My only regret was that I never got to see your product.
