Here is what I think the story of the price and rebate.
1. In Sunday' ads, it shows the drive is $159.99-$60MIR-$20MIR. So that is $159.99-$80MIR. The store price is actually $149.99 and the Maxtor rebate is $30, so BB offer a $40 rebate to make it $149.99-$70 MIR to match the ads price.
2. And then BB tried to match Staples's $129.99 price on Wednesday, then here came the first deal for $129.99-$70 MIR=$59.99
3. Later, maybe someone works for BB website tried to match the $80MIR in Sunday's ads. With the Maxtor $30 MIR, BB then offered the $50 MIR on the web, make the deal hotter for $129.99-$80MIR= $49.99
4. And then, the website guy thought the price is too low, he then explained the $129.99 price is $149.99-$20IR. So the $80 MIR in the ads is like $30 MIR+$30MIR+$20IR. So the deal now is $149.99-$20IR-$30MIR-$30MIR.
My concern is, the three $30,$40,$50 rebates have the same rebate number #37772. I am worried that even using the $40 store print-out rebate form will be honored for $30 only.
