Without knowing for sure, I would hypothesize that eBay is now adding sales tax for specific states when out-of-state purchases are being shipped to that state (i.e. Use Tax), but is still leaving it up to sellers who reside in those states to collect and remit Sales Tax to their state as before. This would make it appear hit-and-miss for application of sales tax for in-state buyers. Did the Wayfair court ruling that all of this was based on even speak to application of in-state sales tax for internet purchases?

I haven't tested this theory. Just throwing it out there for consideration.
