What to Buy at Costco: 100 Bulk Purchases That Save You Money

You don’t have to wonder if Costco has the best deals because I’ve already done the math for you on these 100 best bulk-value buys (including many name-brand items!). Here’s exactly what to buy at Costco with your membership that’ll save you money every time. Each item on the list has the best price per unit when compared with local grocers.

Oh, and in addition to Costco’s everyday low bulk prices, many items also offer instant savings coupons. This means you’re getting an extra discount from the brand’s manufacturer (exclusive to Costco), on top of the discount already applied to the item by Costco. And you don’t have to clip any coupons to get the discount. The price is automatically registered at checkout.

So if you’re a non-couponing Costco lover, rest assured that these are truly the best-priced items — but remember those exact savings may vary depending on your location!
