[quote name='razgriz417']You can use the Gold Box trick @ amazon.com
Stolen from Slickdeals.net...
To get ***40 GB**** in Gold Box for $379 (before -$100) I tried this and it worked perfectly,
1. Created New Account
2. Rated PS3 controller AND "Call of Duty 4: Modern Warfare"
3. Now I had 40 G PS3 in my Recommendations like 7 or 8th Item in addition to 60G and 80G
4. Went to "Recommended for you" and said Not Interested for everything apart for 40 G
5. Went to GB and Sure enough PS3 40G was there for $379.99! And promptly ordered!![/quote]
If it's the same SD post I saw, then it's worth mentioning that the $100 off applies to getting the Sony card. If the $100 discount is something else, then I suppose it can stack with it, since the credit card gets $100 off the purchase anyway, which'd make it a really great deal at the price of a 360 Arcade unit.
