Following quote from BB website. It helps clear up their online match policy. They will match if the item is not designated "web only".
In July I was looking for a FP that was going on close out. Prices and stock varied a lot between the stores. Their price match policy says blahb blah match another BB store in the "local area". That is a vague one that will get you spinning. The best I got from them is local to them means in the same BB District.
They jerked me around when I wanted to buy a product that had the best price and have it transferred to a close by store for pickup. I could never get enough people on both ends to agree to make it happen. I still believe it can be done but the high percentage of iDiots working there make the changes quite low.
What if I find a lower price at another Best Buy store or on BestBuy.com?
If an item you purchased at Best Buy is advertised at a lower price at another Best Buy store in your local area or on BestBuy.com, we'll refund you the price difference from our own sale price, or 110% of the difference from our competitor's sale price, up to 30 days after your purchase (14 days on select categories*, 60 days on HDTVs purchased from 7/27/08 through 10/04/08). Simply bring in your original Best Buy receipt to the customer service counter while that lower price is still in effect. Clearance and Outlet Center items, open-box items or Web-exclusive offers advertised on BestBuy.com are not eligible for price matching.
What is a "Web-exclusive offer?"
It is a product or a price that is only offered to online buyers.
Does Best Buy match prices of Internet retailers?
If you made your purchase in a Best Buy store, and you find an Internet retailer with a local retail store honoring its own online prices, we'll match their price, plus 10% of the difference. Internet-only retailers are exempt from our price matching program, as well as Web-exclusive offers. Eligible items must be the same brand and model, and currently in stock at the competitor's store. For purchases made online at BestBuy.com, please refer to the Online Price Guarantee on BestBuy.com.
