Carabiner's For the One-Trip-Grocery-Shoppers
Use a carabiner to carry in all your groceries at once, because two trips are for weaklings. If you're the type of person who lives by the one-trip lifestyle, then you absolutely need a carabiner. Maybe two, if you can carry bags in both hands. The best part of the carabiner hack is to get a giant one. That means way more bags. Just make sure they're all secure and not ripping!
