The Costco Weekly Insider Deals are back for the week of March 9th! This weeks Costco coupons begin on March 9th and run through March 15th.

It’s really nice to see these deals back after a week of no weekly deals. One of our favorite cheeses at Costco is Kerrygold Dubliner, so it’s nice to see it on sale for $3.30 off per package. There’s a lot of sicknesses going around, so it’s great timing that Kleenex 6 packs are on sale for $3 off. The Costco bakery makes a Kirkland Signature Shepherd’s Pie during the March St. Patrick’s Day season, so that’s called out as a seasonal item. There’s also a couple new items, one being the Nintendo Switch 2 + NSO + Memory Card Bundle for $519.99.

While what’s listed is warehouse pricing, some of these items are also available online for a delivered price. Not everything listed is available in all locations. Pricing may vary by location in Alaska, Hawaii, Puerto Rico and online. Anything that catches your eye this week? Leave a comment and let us know!
