I traded in a lot of 5$ games along with some gifts and Paper Mario... I paid about $50 total for the stuff I traded.
I received $165 approximately for these titles:
Super Paper Mario (Wii) - paid $20, got $45
Mario 64 (DS) - gift, got $18
Harvest Moon (DS) x3 - paid $15, got $54
Cooking Mama (DS) - gift, got $14 (I think)
Gunpey (PSP) - paid $5, got $12.50
Puzzle Challenge (PSP) - paid $5, got $10.50
Block Party (PSP) - paid $5, got $10.50
I picked up Resident Evil for Wii, and tomorrow I'm getting GrimGrimoire for PS2. I'm also going to try going to CC and pricematching the BB coupons on Bust a Move (PSP)... they've been working at BB consistently even though they're expired, and they've worked a few times at CC when expired as well for me. So if it doesn't work, no loss, I'll just buy them anyway and still come out with 2x in store credit.
I'm very happy with nearly a 300% profit (even though it's credit... I obviously buy a lot of games). I'm debating what to get tomorrow... I managed to pick up a Mint condition Stella Deus (PS2) @ $15 today along with Summoner 2 for $8 in addition to RE4 Wii, but I'm hoping to cash in on the B2G1F deal. With anywhere between $70 and $110 in credit tomorrow (depending on my CC journey), I'm going to do a lot of review reading tonight.
