i did the rebate last week to and it was for $10.00, it was a totally different ammount and the dates were different too.
there should be no problem with these rebates, they keep runnig rebate over again for a week or less each time, so every time they do this you can get the same ram again real cheap.
When they had the WDSE 160gigers with a 200giger in the box i got 1 from Bestbuy the first week and 1 from Circuit city the next week , and already got all my rebate for both, because even though it was a $70.00 manufacture rebate for each drive, the one ran for 7 days and the next one ran the next 7 days after that, so they were a totally different rebate.
