Nope, but I do ship things to my mom once in a while because they aren't online. Charlie's soap or a few other items she likes. We don't split the cost, I just send it. I could see where that could look like we "share" but I don't think we do at all. As a matter of fact, DH signed up for his own free trial of prime over the holidays and forgot to cancel before it autorenewed, so now we have two prime accounts :/
