On Thursday afternoon, and with over a day left before the auction's end, at least two eBay users were in a six-figure bidding war over one tee on sale.
Four other "Massacre" T-shirts also with active listings on Thursday were selling for $100 or more.
Meanwhile, here's the donations page for Boston's Beth Israel Deaconess Medical Center, where victims of the bombing were treated.
Because $155,000 could be spent a lot better than on a used and quite likely sweat-stained T-shirt. Just saying.
