So you want an iPhone X so much you're willing to preorder the thing. The only question is where.
Best Buy's higher price only applies if you pay the full price up front. If you pay over time, pricing is basically the same as on Apple's site.
"Sometimes customers aren't able to purchase phones at other locations because their desired plan or carrier makes them ineligible," a Best Buy representative said in a statement. "That's not the case at Best Buy, as our prices reflect the fact that no matter their desired plan or carrier, or whether a customer is on a business or personal plan, they are able to get a phone the way they want at Best Buy. Flexibility has a cost, but it's something our customers have told us they want."
The retailer also charged more for preorders of the iPhone 8. At the time a company representative told customers on its forum that the phone is not eligible for price matching, and couldn't explain the higher price.
