Oh, no. I didn't do a price-match "claim" to amazon. I just emailed them and asked if I could still get the rebate even though I didn't technically qualify for it by 3 days. Amazon replied back that the rebate is with the manufact and to check with them and sent me a link to download the rebate (pdf) and the contact info to logitech. I sent in the forms and Logitech honored the rebate.

I was just using my experience as an example that it doesn't hurt to ask for a price match if you have already bought the micro card and the price dropped significantly. The worse thing they can say is No. It being a third party but through amazon marketplace, Amazon may refund you the difference or issue your account Amazon credit towards future purchases.

Edit: Just checked original link. Patriot card just dropped 5 bucks.
