Anyone had any experience with FrogPrints.co.nz?

I just made two purchases tonight, they both gone through sucessful. And it showed me the "eftpos" like invoice page, but not telling me to print for keeping record. So common sense indicate that, they will automatically send a copy of the invoice for safe keeping, even on their "successful order" it said an email will be sent to confirm purchase order.


20mins later, still no email confirmation.... How weird is that?
