We have 4 children and we go through a ton of groceries in a week. I managed to get several items from Sam’s Club in one bag (a box of 36 poptarts, a big box of individually wrapped crackers [30 or so], bananas, a large box of oatmeal creme pies [24 pack of the large size] and so much more)! I can usually get all of my groceries from Walmart to fit in one bag – which includes cereal boxes of ANY size, breakfast bars, seasoning packets, dressings, chips, all of the Easter Candy – you name it, it fits! When I go to Meijer, I can fit 4 gallons of milk in one bag! It is very heavy (40 lbs) but it beets making several trips to the house.When our family goes on vacation, we use these bags for the food items we bring in one bag, all of our bathroom stuff in another bag, a ton of bottled water (16 bottles or so) and other drinks in another bag, toys for the children in yet another bag, and whatever else in the other bag. This has cut down on several grocery bags we use to take along in addition to our suitcases full of clothes, diapers, etc.I just tried washing the bags for the 1st time this week since I have had them for a couple of months now. I have a front load stackable washer and drier. I put it on the hand wash cycle because I wanted cold at low spin speed. I even threw in the plastic bottoms and they came out very nice and clean. I DID NOT PUT THEM IN THE DRIER, I LET THEM AIR DRY AND I WIPED THE BOTTOMS OFF WITH A CLEAN HAND TOWEL/WASHCLOTH. I don’t know how well they would wash on a temperature other than cold because I don’t want to risk shrinking them. If anyone has washed them on Warm, please let me know how they came out as I would prefer the temp if they don’t shrink. The bags came out stiff still so I was very happy with my results.I really like that these bags stay up straight when you are loading them. They make shopping and bagging a breeze!
