How to buy Apps without having a phone?

[FelipeRRM]

I sent my phone to reapair, and it'll be there for some months (Sony Ericsson is very slow) and I bought a GS2, which only arrives next week. But there are some apps on sale on the market that I want to buy, but I can't!! Why doesn't Google allow buying apps without having a phone, even through it's online market? Is there a way to overcome this?

Already tried to set up the Android Emulator, but as it doesn't come with the Market it didn't help. Please, help me!!

Thanks guys!
