AMEX Blue Question

[Hitokiri Battousai]

I've recently bought a monitor at buy.com for $420 shipped. The monitor actually costs $410 and I used a $25 coupon to alleviate some of the shipping charge. I saw the same monitor advertised elsewhere for $340 but costs $380 after shipping. Will they use the former or latter price for the final pricematch? Thanks in advance.
