My mom lives in NYC, where the sales tax is 8.875%
She just bought an iPhone11 over the phone from her carrier, Consumer Cellular, which she had shipped to her house. The sale w/shipping was $710, meaning the sales tax should have been $63.01. But it was actually $111, brining the total sale to $821. The customer service rep said she could not explain why the discrepancy, that "they go by what the sates mandate".
I know that with some things, car rentals for ex., you pay not only the sales tax, but additional taxes as well. Is there something similar with cell phones, or should a cell phone be the basic state sales tax rate?
Thanks in advance.
