My inner nerd is probably showing (again - as if my outer nerd isn't enough), but I can see this happening when you upload a huge list of Musical Instrument Accessories to sell in your Amazon store, and you don't specify what instrument they are for, and it defaults to the first one in an alphabetical list of options.
Yeah. When I was self employed I got a gig where this guy was trying to get over a thousand different area rugs into his client's web site shopping cart. I got paid to find a way to automate it. I can see this happening (unless you hired me. Heh).
