Costco Just Put These 9 Online Items on Sale

From coffee to kitchen appliances, here's how you can save big this week.

There are more than 100 million Costco members around the globe. While shopping inside a warehouse is an always option, being a part of this club also grants members access to exclusive sales on

There's no shortage of these sales either—members can expect to see discount events happening every few weeks. In fact, you can shop the new "Online-Only Hot Buys" sale from Monday through Friday of this week.

We rounded up nine items that members may want to add to their kitchens during the latest online savings event. FYI: The sale also includes clothing, electronics, home goods, and jewelry—in case you have an eye on any products beyond your pantry. (And for more, here are 6 Things You'll See at Costco This Year.)

Nature Made Vitamin C

Costco is putting some supplements, such as this bottle of vitamin C, on sale for $8 off. Vitamin C helps the body heal and repair wounds, and it can also improve heart health. And that's only a few of its many benefits—here's What Taking Vitamin C Every Day Does to Your Body.

Just one of the 1,000-milligram tablets includes 1,111% of the daily recommended value of this vitamin. That's on the higher side—while experts recommend not exceeding 2,000 milligrams a day, keeping an eye on the rest of your diet throughout the day works. Side effects of taking too much Vitamin C may include cramping, diarrhea, kidney stones, nausea, and even insomnia.
