My wife bought her phone from Best Buy for $50. She paid sales tax on $50. She bought the same phone for our son from Verizon two weeks later because it was no longer on sale at Best Buy. The phone was on sale for $170 minus the $70 rebate that brought it down to $100. However, Verizon said they'd have to charge her sales tax based on the full price of the phone, which was $359.

Why did Verizon charge sales tax on the full price but Best Buy did not? Is this a scam on Verizon's part?
