Help regarding RAM, kinda stupid question.

[Cam42]

I know the MacBook Pro's RAM is dual channel, which benefits from 2 like modules installed but... Could I purchase 1 4GB DDR3 module, install it, and have 6GB RAM?

Yes, check this out at Other World Computing

Which MBP do you have?
You can see all of the options here

Don't have one yet, but I'm thinking that I don't want to cough up $600 for 8GB, but would like more than 4GB.
Also, it's 2x2GB in the new MBPs, so couldn't I just get away with purchasing one 4GB stick, and keep one of the 2GBs?
