Why pay $70 after MIR?
Staples has this drive (or one similar enough for pricematch) for $100. Best buy has it for $130 with $30 MIR and $20 GC. I got the drive, got both rebates, brought Staples ad next day (well, not Staples ad, but a printout from instorespecials.staples.com site). BB guy called Staples to confirm price and I got $33 PM back (I guess BB is getting on the 110% PM deal). So, total after 2 MIRs is $47 plus tax.
I did it this week, on March 3rd and March 4th, so deal is still alive.
