I just got this email from Amex Blue, looks like there's no more price matching!!!

"Please be advised that as of May 1st, the Best Value Guarantee
benefit will no longer be available on the Blue from American
Express Card. This benefit enabled Blue from American Express
Cardmembers to shop for the lowest priced items by refunding the
difference* between the item purchased and any covered item**. The
program will cease for purchases made with Blue after April 30, 2002."
