Costco’s Kirkland Signature store brand has a huge cult following, and it’s no wonder when you compare the savings.

Here are the 20 items you should never buy name brand again:


1. Buy Kirkland Signature outdoor trail socks instead of Smartwool Hiking socks.

Smartwool might be the high-end choice, but Kirkland offers a quality wool blend hiking sock for way, way less. You pay just $9.99 for four Kirkland pairs instead of $15.90 for a single pair of Smartwool socks, making Kirkland socks the no-brainer choice. After wearing both I can honestly say Kirkland socks kept my feet just as toasty.

  • Kirkland Signature outdoor trail socks: $2.50 per pair
  • Smartwool hiking socks: $15.90 per pair
  • You save: $13.40 per pair


2. Buy Kirkland Signature pure maple syrup instead of Roxbury Mountain.

Pure maple syrup coupons are few and far between, which means you need to get creative to find deals.

Look no further than Costco, which sells 100% pure maple syrup for only $0.30 per oz, almost $1.40 cheaper per oz than Roxbury.

  • Kirkland Signature pure maple syrup: $0.38 per oz
  • Roxbury Mountain pure maple syrup: $1.77 per oz
  • You save: $1.39 per oz


3. Buy Kirkland Signature pure vanilla instead of McCormick.

Is it just me, or has the price of vanilla gone way up?! Pure vanilla extract at imitation vanilla prices can only be found at Costco.

  • McCormick pure vanilla extract: $2.00 per oz
  • You save: $1.00 per oz
