I did the trade deal at GAME - trade 1 selected title and receive $80 credit towards this game.
Likewise. I traded Wolverine, which I originally paid $78 for and completed twice. Thus I was ahead by $2.
Then today at university, there were "goodie" bags scattered around campus. This appealed to my frugal nature, so I picked one up. The bag contaiend a book of coupons, and to my delight, one coupon was a Game voucher for 20% off. Applied to the $150 collector's edition, the price would be reduced to $120. Subtract the $80 trade value, and I'll be left having to pay the remaining sum, a paltry $40. That's supposing Game honour the coupon, which I see no reason why they shouldn't.
Overall, I'd say that's pretty good. Not to mention that this game looks to be the diggity.
Edit: By the way, the university is Newcastle. So if anyone should be a student there, I'd suggest having a look for the goodie bags.
