It can be tough to leave Costco without a shopping cart overflowing with stuff. From home goods to snacks for the kids, you’ll find virtually everything on the store’s towering shelves.

Diehard Costco shoppers know that merchandise rotates frequently to keep a fresh selection on the shelves — and to keep shoppers coming back. The store also moves items, often, causing you to walk the whole warehouse looking for your favorites and grab up other sale items along the way.

But experts note there are some items at the mega warehouse club that just aren’t worth the money. You can save time and money by doing your Costco shopping online, without all the temptations in the store.

Alas, you’ll miss out on the free samples or the tradition of ending your trip with an all-beef hot dog and soda for just $1.50, which is truly an inflation buster.

What, then, are some of the other Costco buys that are worth your hard-earned dollars? Take a look at these inflation-busting sales this September 2023 at Costco.

But, if you’re a Starbucks fan, it’s hard not to stock up on a variety of Starbucks favorites, including Sumatra, Caffe Verona and Pike Place Roast for $36.99 for 72 cups, a savings of $6 off Costco’s usual price.
