They did exactly this to me on a Dell Spectre laptop at the Bellevue Best Buy this year, and it felt very dishonest to me, since the items were clearly 100% identical except for some mysterious tweak to the model description. They also tried to get me to sign up for a credit card for a big discount, then denied the card despite my nearly perfect credit score. Weird experience... I have also found that their price matching is dishonest and inconsistent, and you have to be prepared to just drive to another store or come back another day. That said, I still shop at Best Buy because their website is accurate and usable, and often the demo products in the store actually work.
