At one point a couple of years ago, I received an unexpected delivery from Amazon, containing a bottle of PreSeed Fertility-Friendly Lubricant. This surprised both me and my fiancee, as I hadn't ordered it, nor would I order something like this, as my fiancee and I are deliberately not trying to conceive a child. (For one thing, she has DVT and is on Coumadin; a pregnancy would be potentially life-threatening for her.)
Checking my Amazon order history, I found no reference to any such order, nor did I find any reference to the order number on the invoice. I E-mailed their customer support, asking how I could return this item, since I hadn't ordered it and didn't want to be charged for it. They replied, saying that the shipment was in error, I had not been charged, and due to the nature of the item, they couldn't accept returns on it.
I wound up offering it to my Facebook friends, and shipping it to a friend in Illinois that spoke up first to claim it. She didn't say why she wanted it and I didn't ask.
