It can be a good bug...I send sims to buy groceries at a store and they're able to purchase as many baskets as they want. When they get home don't allow them to put away the groceries. Once they set them on the ground just stuff the baskets in inventory and take them out as needed.
Hey, that's a great idea. I'll have to remember that one. I never buy groceries on community lots, but I will have to do that now when my sims are there. I usually get the delivery guy, but sometimes I let the fridge get empty at the most inconvenient times, like when my sims are in hunger desperation. I hate to buy new fridges, so this would be a better option to stock up on groceries.
