It would have to be something whereby we, the user create the code and set it to 'voucher' or 'coupon' code'. ( voucher being a one-use item and coupon being something we could put in an advertisement on our websites / advertising venues )
Otherwise a decent hacker ( or a script-kiddie ) with a listener bot set to shapeways could get the code and use it themselves... just sayin.
( also, sidenote: if we could key the vouchers / coupons to a particular item that would be freaking sweet... particular item vs. our whole shop )Welcome to Costco, I love you.
