I'm in the field myself (see profile) and although the website looks nice I don't see how it's different than any of the existing services.<p>Here are my $0.02:<p>1. PRICE - The prices are way too high. Especially given that all established print services offer huge discounts these days. Even our Printy.pics iOS app offers lower prices + 40% discount.<p>2. Registration - I would prefer to register when I need to (before payment) and not when I'm asked to. The common practice for most web print apps is to allow product creation and require registration (if at all) on checkout. I guess you should do some A/B testing to see which approach maximizes LTV.<p>3. Why .io?<p>On a general note, it is very hard to compare print products. There can be huge quality differences and for someone who isn't an expert in the domain it would be hard to tell if the price is worth it.
