<< I don't have AMEX, but thinking about getting one. How do you price match using AMEX, I don't understand. Is it like doing a price match using a reciept. Thanks >>
No, it's not in store. You call AMEX up after making the purchase, then you fax or mail them copies of your receipt and the dated ad or website advertising a lower price. Then if they approve it, they send you a check.
Since AMEX changed their policy about multiple matches, it's probably best to buy the drive now, then wait 6 or 7 weeks before price matching to maximize your PM. The only problem is, you have to wait for the PM cash back. If you think about it though, that's not as long as most rebates take to get back to you.
These days, I buy almost everything with Blue, just in case I want to PM it later. Blue also extends the warranties on almost everything. There is a limit of 4 PM's A YEAR, so I try to only PM on things that come close to the PM limit ($250 each). This is a borderline Blue PM, even though its $100. I think most deals posted with a $20 or $30 Blue PM don't make much sense. Unless you don't plan to buy anything expensive, you're losing out on $200+ in PM, if you PM for piddly amounts.
