<< Yep
You can buy a 10000 purchase and get $1000 GC back.
let's say you buy 30 PS2, $300 each => $9,000. You get $900 back. Sell them back on Ebay for $290 shipped each (trust me, u'll be able to sell it at $290) => $8700.
-$9000 + $8700 + $900 => $600 >>
Unless you live in a state that doesn't charge sales tax, you'll be losing money each time you sell one. I live in Texas and sales tax is ~8% for me. Here's your math.
-$324 = PS2 + 8% sales tax
+$30 -- $30 Circuit City GC
------------------------------------
-$294
+$290 -- PS2 Sold on eBay
------------------------------------
-$4
-$8 -- shipping on PS2
------------------------------------
-$12
-$9.87 -- eBay fees
------------------------------------
-$21.87 loss on each PS2
If you live in a state without tax, you make a whole $2.13 per PS2!
Yep, fuzzy math must be great if you don't plan on following through.
