Part of all of this, too, is just the desire for time savings on the part of the seller. A large, well-known shop with a presence on eBay sold me a Brooks saddle, but they'd crafted general-purpose ads for that model of saddle, not distinguishing the specific features of the specific saddle sent to me. Ad was specific about having X feature, but I got Y feature; same saddle model, but different feature. They've got hundreds of ad listings they create, at any given time. I'm sure they don't open each and every box, and I'm sure the photos/specs used aren't specific to each and every boxed item individually. To the detriment of the buyers, now and then.
