Xbox 360 game postage question

[Drake5]

I'm just wondering if I could use 2 X 1st class stamps to post a Xbox 360 game in a giffy bag as I have 2 laying around and it'd save me a trip to the post office.

Obviously I don't want the recipient to pay for the postage so I just thought I'd ask as I wasn't sure!

Cheers

I don't understand that, I have no idea when it comes to postage at all lol. I assume it will be classed as a large letter, so that means I will require a large letter 1st class stamp? I know large letter 2nd class stamps exist as I've used them before for this sort of thing, but I'm not sure if 2 X 1st class stamps class as a 1st class large letter stamp.

Confusing, I know!
