Show HN: CasePlum – Custom-printed iPhone 6 Cases (Passive Income Idea)

Hey guys, made this site in 2-3 weeks, just in time for the iPhone 6 launch. Thought it'd be an interesting passive/side income idea, which I know is a popular topic on HN.

Apologies if its buggy or doesn't support certain browsers/screen sizes. Trying to be lean develop it

Also, since the community here is great and has provided excellent feedback before, here's a $10 off coupon just for you guys: HNthirty.

Any tips on how to market it? I'll happily share numbers with the community if it goes anywhere.
