How I got screwed up by Google Checkout

First of all - technically, it was my mistake.

I registered an Android Developer account, configured Google Wallet with my VISA, paid the license, and developed an app I hoped to make money from. This took 2 months.

The product is almost ready, when I decide to get a closer look at the "Upload application" section and I realize that Google Checkout is not supported in my country (Bulgaria).

Yes - I did not research that before I started the project. But I wonder - was it stupid to make the assumption that one can sell his/her app in one of the world's leading software markets from an EU country?

Or is there something I'm overlooking?
