That's what I thought would happen but it didn't. The app I was buying was one I had already purchased months ago for another device (on the same account). When I clicked on the "install button" to send it to my Nexus 7 it just went to the screen that said it was installing. When I go to orders and settings and the bottom of my Google Play page, I see it as a 99 cent purchase. I also never received an email confirming the purchase. I go into Google Wallet where it lists all my purchases (including the Nexus 7 itself as well as every app I purchased for my other device), and there is no reference to the purchase of the app. I do see my credit card info and the $25 credit as a separate payment option. I'm wondering if there is a bug that with some apps if you have purchased it for one device, you can install it on another device without further charge. I wouldn't think that would be intended, but it's about the only explanation I have.
