Best Buy (or as I call them "Pest Buy") will match the sale price of the item only. They cannot match Amazon's price once local sales taxes and any other add-on's such as extended warranty are added to the product.
If you're looking to buy a TV and "want it now" then you accept that you're going to get the same sale price on the TV but by purchasing locally you're also going to pay any sales taxes (which are outside of Best Buy's control) or delivery charges (if you opt to have it delivered to your home vs. taking it home yourself and not incurring that charge.)
If you're trying to get Best Buy to match price vs. Amazon, Best Buy will always be at a disadvantage once local sales taxes are included in the price. They're not going to eat the sales tax to match price with Amazon when buying from Amazon means no sales taxes. It's just not a realistic expectation of Best Buy.
(Disclaimer: I buy almost exclusively from Amazon and haven't stepped foot in a best buy in 10+ years. I refuse to pay Illinois Sales Tax, which is why I shop Amazon for everything I can.)
Amazon has a distribution center in my state. We get charged for the sales tax for Amazon orders.
You can’t blame BB for having to collect sales tax, they don’t get to keep it, it goes the state, and they have to collect it by law.
You know what else? That purchase on Amazon, you are bragging about not paying tax on, you are in most cases SUPPOSED to self report at the end of the year when you file and send in the sales tax... So that’s apples and oranges.
As to the extended warranty you choose whether or not to buy that, so again, that’s an unfair comparison.
Not defending BB here, but seriously, expecting you are can get them to eat the tax and give you an extended warranty for the same price you saw advertised on amazon for the item is silly.
