What I used to do when my oldest two were smaller, was first, we would go to the section I knew they loved the most(sometimes it was books, sometimes toys, sometimes candy). I would let them pick out something they wanted and even hold it the whole time we were there. Touch it, love it, play with it, show it off to the kid in the next cart, whatever. I told them from the very beginning that if I had to tell them more than two times to behave, or if they pitched a fit ONE time, I'd take it away at the cash register. A few times of that, and I never had problems again--except the one time my son smacked me. Yep! He smacked me, and hard. I think he was maybe two at the time. Oh yeah, he surely didn't get his toy, and when we got to the car, he learned such an effective lesson, he never smacked me again. But talk about being embarassed. The cashier herself, told me if it was her, she'd whup him right then and there. I told her thanks for her concern, but I'd handle it later.
Anyway, I've seen some good suggestions here, and I'd say(imho) the best is either the rewards suggestion, or the leaving them at home suggestion. One other thing you could do, is send your hubby off with them all to somewhere else, while you go and do what you need to do. Since he seemingly thinks he'd manage them better. My hubs would take the kids and go to electronics, the hardware section, the sporting goods section, or somewhere else equally boring. Lemme tell ya, they appreciated me muuuuuch better when they came back, except when they went to electronics. Video games there, ya know.
Anyhoo, my youngest I have never had any problems with(when she was a baby, she had colic and I NEVER went to the store with her, or anywhere else for that matter), and my son(now 15), ironically likes shopping much better than my oldest daughter, who will only go if she reeeeeeeally needs something, or is reeeeeeally bored(ironic for a 17 yo girl, eh? Thank GOD!), and is actually very budget conscious and a good bargain hunter. I usually take him shopping with me when I go get groceries, and I prefer it over taking my husband. My son knows where everything is, reads labels better, and knows the routine.
Personally though, like someone else said, unless it's a trip especially for them, or you really need a helping hand(we bag our own groceries where we shop--I NEED extra hands) I'd use that time more for me and some "get away" time. Or better yet, shop with a friend. Do lunch, get a pedi, too! :o)
Whatever the case, I hope it gets better soon.

P.S. And if you want to see a kid acting reeeeeally bad, check out thi site: http://inthemotherhood.msn.com/?source=MSN_FamilyParenting , and go to the one titled "Preachers, Panties, and Police." Yeah, you think *you're* embarassed lol. Oh, and "Nightmare on a Plane." Her kid is the DEVIL!
This site is a great way to laugh at motherhood. Not too terribly realistic, but somewhat, and DEFINATELY funny and a nice little break. :o)
