Soda
Savvy shoppers swear by grocery stores instead of warehouse stores when it comes to buying their favorite sugary beverages. While Costco allows you to stock up in time for birthday parties and football games, their prices are higher than what can be found elsewhere. Most 12-packs of soda (normally around $4 – $7.49) are featured during “two for the price of one” promotions at local grocery stores while Costco sells 24-packs for $7.58 each.
