Thinks s/he gets paid by the post
I just looked at the spreadsheet download from Amazon. I occasionally send gifts to TN and, for those purchases, the tax is at the rate in the city in TN I send the gift to. For the ones delivered to me, the tax is at my city's rate. I thought Amazon charged tax on everything sent to me since they are WA state too but I see some exceptions where no tax was paid. They have columns that seem to be for assessing the taxability of the item but all three tax exemption columns are empty. I bought some food and food should be exempt in WA but the columns were empty for these too. (Maybe the columns were provided for the buyer to fill out.) I'd be willing to bet that, if I checked it, the items taxed are those that are linked to Amazon's "fulfillment center" for returns since they are the main trackers of the merchandise.
Check who the seller of the item is in many cases it is an
Amazon associate not amazon.com. If it is sold by Amazon.com you pay sales tax, but if not you may not, some items you find listed as fulfilled by Amazon, and others you find that Amazon serves as an order taker only.
