Last Chance: Top 10 Grocery and Household Deals at Costco

Here are the top 10 deals ending Sept. 21 at Costco.

A 24-pack of Activia yogurt is on sale for $6.39, which breaks down to just $0.27 per cup. It’s a good deal compared to Walmart, where a 4-pack sells for $2.98, or $0.75 per cup.

It’s your last chance to stock up and save on household essentials like Tide, Gain, Charmin, Olay, Venus, Swiffer, Cascade, and more.
