Will they have their own "defect rate"?
This part is the funny one
" the top predictors that a buyer will leave eBay or buy less: "
1) Ads that effectively disable the back button. Unless you block them then going back only takes three clicks instead of 60. (Partly fixed for IE11, and not a problem with firefox.)
2) "best match" --I've never been able to figure out just what the heck they're matching the items with. It's not usually my searches.
3) Stuff posted outside the proper category. pre 1942 is when the card was made, not when the player pictured on your reprint played.
4) removing the sections for memorabilia for a wide range of sports and putting them all under "other" Which seems to be the category if you want "fitness" magazine pinups or NFL calendars. (which really should be under football-NFL)
5) Blocking international listings unless it's from some place in China trying to sell the same knock-off stuff for a dollar less than the other places in China.
If I want that junk I'll go to Wal-Mart.
