Anyone else get a tax statement from Summit Racing?

And many sellers are confused or using the change as an opportunity. I won an Ebay bid last week for an item and the seller added 9.5% sales tax as they are in Oakland, CA. I messaged them that my states sales tax is 5.25% and they said they now have to charge 9.5. I also called a place in Seattle to order some parts today and they were going to charge me 9.6% tax. I told them my state has 5.25% state sales tax and they told me they were required to charge the local tax. They said the new law is written that tax is charged at the point title to the goods transfers. In Washington goods transfer at the point of sale, not delivery. When I told them I would pay 5.25% but not more they politely declined my business.
