This is the deal of the century. I bought six 4 gig Sandisk Extreme III cards. With the rebate they were $13 each. I handed all the rebate stuff over to Ginny, of course. I am not certified to fill out rebate applications and I am certainly not qualified to actually receive the rebate.
Don't be too concerned John, the chances of actually getting the rebate is very low. By the time you have sent all the 'correct' documentation, which changes with every communication, you will have exceeded the time limit.
