They advertise special has the Maxtor 120GB ATA133 2MB Cache for $139.99 with $40.00 rebate.

Guess what? You can pricematch it!

Add the 256MB PC133 SDRAM for $39.99 - $20.00 rebate = $19.99

Use the $30 off $150 coupon!!!

Total is: $179.98 - $30.00 coupon - $40.00 HDD Rebate - $20.00 RAM Rebate - $20.00 PM w/ CompUSA = $69.98 + tax!!

Not a 8MB cache but cheap.
