Update:
I just called Staples CSR to pricematch Maxtor 40GB
When I try to use the coupon, the CSR said it's for Yamaha CD-RW just like Dantzig said
and btw, it's out of stock if you thinking about getting it.
But, if you order directly from online, the coupon works
Although I don't know if there's a problem or not if they know about this
looks like Maxtor 30GB $169 is the one to go
or can anyone find something better ?
