State Sales Tax Holidays: Will Dell honor state sales tax exemptions?

Numerous states offer sales tax holidays during July-August 2025. These include computers and accessories.  Here is a comprehensive list:  Sales Tax Holidays by State, 2025

I live in a state with a sales tax holiday.  I added a computer to my cart but Dell is still adding sales tax when I proceed to checkout.  Will Dell honor the sales tax exemption?  If so, how do I proceed?  Thanks!
