It's not really a problem in brick and mortar stores. It's a problem in online stores because you can't necessarily give someone the right price with taxes until you have their address.
And this problem is harder than some might think. I knew someone who lived on a street that was a "dividing line" for this stuff: same zip code, same city, but one side had a 9% sales tax, the other side had around 7%. We tested a lot of online stores and none of them got it right. Including Amazon.
