I'm severely disappointed in your price-match guarantee policy. It didn't work for me. I'm going to tell you what happened, and then I'm going to make a suggestion to make it work for your customers because right now, at a customer's point of view, it doesn't work and Best Buy is letting big sales walk out the door.
I went to the Tacoma, WA store on 48th street on 8/31/2014 prepared to spend $1,896.95 on a Nikon D610 that I need for my business. Best Buy is selling it for $1,899 and your competitor, B&H (who is listed on your approved price-match guarantee list), is selling it for $1,896.95 along with a 16GB memory card, an extra battery, and a DSLR shoulder bag all for free with the purchase. Also, the price on the B&H website is what you pay (no tax or shipping). So I printed off all of the B&H paperwork and brought it in to the Best Buy in Tacoma, WA expecting to purchase the camera for exactly $1,896.95 since you have a "Price-match guarantee." Yeah right. While Best Buy was willing to take $3.00 off of the price, they did not offer all of the free stuff that B&H was going to give me, plus they were going to charge an extra $180.21 in Washington state sales tax. As a customer, the prices $1,896.95 (plus free stuff) and $2,077.16 DO NOT MATCH. Therefore, I took my money out the door and purchased the camera from B&H over the phone in the parking lot.
What I suggest to make it a true match price guarantee is to bring down the price of the product so that when the state sales tax is added, the total will be the price of the competitor. Best Buy is letting huge purchases walk out the door because in states where sales tax is added, it increases the price dramatically. This fact is not listed in any of Best Buy's "Price-Match Guarantee" rules. It's silly. Why would someone spend almost $200-$300 more when they don't have to with your competitor?
Anyways, I look forward to getting my new camera from B&H shortly!
