I was really wondering if this issue would come up. I too feel uneasy about this, just a bit. But, it isn't me and my conscience here. It is up to the buyer. That said, I think I'll stick my neck out and humbly suggest that, again, if it were me, I would consider doing something nice for this woman. She , unbeknownst to herself, gave the OP an extremely good deal on this stuff. Whether she knew what the stuff was worth or not, it's done now. But, if you get the chance, do something good for her if you can.
