Still not as much
In the US, Our sales taxes are low compared to VAT. A few states have no sales tax at all, some are as low as 5%. and the highest being around 9% base. Some cities and counties add their own sales tax, but that's up to them. Overall though, the average sales tax is around 7.5%.
Also, when shopping online, many people here in the states don't have to pay sales tax on online goods, although several states are passing laws requiring sales tax to be collected by online retailers no matter where the retailer is.
