Costco… the only place where you can spend over $100 in groceries and still have to go to the grocery store right after. But where else can I get 3 gallons of peanut butter for under $10? We all know we secretly go for the free food samples and that delicious $1.50 hot dog and drink combo. So, I had the idea to build a shopping cart attachment for all my Costco trips. Equipped with a drink holder and tray big enough for a Costco size hotdog. And when you get tired during your Costco visit, you have a soft cushion handle to rest your forearms on and push the cart around. What else can I add to the Costco food tray? #costcofinds #DIYideas #DIYHACKS
