I make no judgment on people who do or don't.
I don't mostly because I don't have the time to spend in the store. I need to get in and get out before my kids go nuts (or if I manage to go with out them, back because someone is watching them.) Either way I don't mess around with it in the store. I used to pull it back, but now I just look them over and feel them in the store, it seems to work for me. Also what many people say, it stays fresher that way. I try to buy corn the day I eat it, but it doesn't always happen that way. I ate some yesterday we bought 3 days before (husk on) and it was GREAT! (Good time of year for corn.)
If I was only buying one to 3 ears maybe, but I tend to buy a bunch. Everyone loves it, and corn on the cob is the only veggie I can get Little PhD to eat currently.
My stores normally provided the bins. I don't like back log trying to pick out corn though.
Never buy the pre husked corn. It isn't as fresh or good as the stuff in the bin.
