1st GameStop:
80GB phat PS3 (2 USB) -- $90 base, $180 after promo
512mb phat X360 arcade -- $55 base, $110 after promo

Bought a PUR Pro membership, but this GS wouldn't give 30% preorder power trade on accessories (games only) so I went to another GS

2nd GameStop (took a print out of the offer on their website, no hassle):
Preordered COD Black Ops 2
PS3 DS3 wireless controller -- $27.50 base, PUR $2.75, 30% $8.25 = $38.50
X360 wireless controller -- $20 base, PUR $2, 30% $6 = $28
X360 play & charge kit (black) -- $8 base, PUR $0.80, 30% $2.40 = $11.20

$77.70 total credit - $59.99 game (no tax) = $17.71 balance transferred to card

Had another 360 charging cable, but neither GS would take just the charging cable by itself (both wanted a battery pack with it)

Overall pretty happy with the trade -- will wait til Black Friday to buy a slim 360 and super slim PS3
