I recently won an auction for some jeans. The seller lives in Ontario, Canada. In the invoice she sent me, the seller added a few dollars for California tax (which is where I live). In the auction, there is no mention of any tax to be collected. Also, this seller is in Canada. Is there any reason she should be collecting California tax? I paid it (small amount) and questioned the seller but she sidestepped the issue. In the big grand scheme of things, this is definitely not a big deal, but I'm wondering if this is a sneaky way to get more money for the seller.
