Hey, I tried your app but didn't order a card. Here's why:

I had to manually enter addresses instead of being able to select them from my address book. This is really annoying, I'd rather have only the option to select pcontacts than being able to enter custom addresses

The second reason is I had to enter my CC info to orde a card. I'd rather do this through inapp purchases and then wouldn't mind paying a dollar more for it.

Finally, 4-6 weeks delivery really is too long for a "I'll just send a card from my vacation location" type of thing.
