In general, retailers sell new Apple products at the sticker price set by the tech giant, but if you want to buy a new iPhone through the Best Buy website you might end up paying up to $100 more than what you’d pay elsewhere.

9 To 5 Mac reported Thursday morning that Best Buy is charging $50 to $100 more for the new iPhone 7 devices.

A look at Best Buy’s website shows some confusing pricing for the starter 32GB iPhone 7:

While the installment pricing offer of $27.04/month for 24 months comes out to the actual $649 price of the phone, for some reason Best Buy is charging $699 if you want to buy the device outright.

Similarly, Best Buy’s installment price for the iPhone 7 Plus is the same as Apple’s $769 sticker price, but the buy now full price is $869 — $100 more than what you should be paying:

Apple’s website confirms that the company has not changed the retail prices on either of these devices:

9 to 5 Mac notes that the markup price at Best Buy isn’t entirely unusual, as the company has done the same with previous version of the iPhone.

While the markup could have been the result of a supply and demand issue — some iPhones were difficult to find when first released — the devices are now more readily available at Apple stores and online.

As 9 to 5 points out, the discrepancy between the installment price and Best Buy’s price is likely due to the fact that the wireless providers determine the installment rates. So if you’re going to purchase a phone through Best Buy, that installment plan seems to be the only way to get the better price.

Consumerist has reached out to Best Buy for comment on the pricing differences. We’ll update this post when we hear back.
