Really, is that 13 even or 12.99 or 13.99? Well, anyway, nice deal, although I have to think if it would be better to get 90 for 25.21 (with 6.75% tax here in IL) at CompUSA and then try to get $18MIR. If I get lucky I'll get 18MIR if not then I'll get 90CD-Rs for the same price as K-mart has for $13/50pack spindle.

Hm... scratch what I said before. Did some quick math and it seems that CompUSA has the best deal ATM. I dunno if you have to send in one rebate or three separate ones, but even if you don't get them you still wind up with cheapest per CD price, if you do get it... then the price ratio is still the best around.
K-Mart
13*1.0675/50=$0.28 per CD no rebates
CompUSA
(3*10.99*1.0675-9.99IR)/90=0.28 per CD and then $18 if you are lucky.
BB
(19.99*1.0675-3)/50=$0.37 per CD and then 4 and 10 MIR
