I highly suggest you all try out this wonderful, wonderful website.
On my package, I pay some £9.73 and get 4 games a month, and I'm allowed 2 a week, which averages out to one a week.
Their service is solid, with games usually only taking a maximum of 3 days to arrive, with Halo Wars which I recently got, it was sent out on the 24th of April and I received it on the 25th.
You get a trial of 14 days when you first sign up, but, if you follow these instructions by first entering the code "RAFELF14", and then enter my email adress "ohnoes__@hotmail.co.uk" (I'd suggest copy and pasting that) in the registration form where prompted then you'll get 30 days free instead of the usual 14 days.
I used to buy a game every month, and was sometimes dissapointed (Bioshock >:(... ), but now it doesn't matter a huge amount with that because I can just get another game by spening about a quarter of what I would have.
