I saw this trick on a site. Here is how it works :
You sign up for the Amazon Visa Card. Sign up here . They approve you, and you get a $30 discount on your first purchase. Throw ur card away after the purchase. ;).
Then you go to Lexar 128mb . The card was originally 89.99. There is a 48% savings. So the new price is 42.98. On top of that 42.98 we have a $15 mail in rebate. So the price is a mere $32.01.
You then use your $30 credit , and you got urself a 2.01 dollar card!
You can use this on other products too.
