358: grab a cart and dash around the aisles like you're possessed by a race car, snatching everything you can on your way. Proceed to run out of the Walmart with your haul and when they try to stop you, say you are a contestant on the revived gameshow supermarket sweep, so everything in your cart is free because you collected it all in under 2 mins.
340: go to electronics grab all the extension cables they have, connect them to eachother as well as every blender in the kitchen appliances aisle. Fill all the blenders with vegetables and then plug the last extension cord into the nearest outlet. Declare the Walmart a new soup kitchen.
