This week brings a solid mix of deals. It’s nice to see all the new items coming to the Costco warehouse, such as the summer items like the TYR Adult Swim Goggles and the landscape fabric. If you’re a consumer of the Kirkland Signature Baby Wipes this might be a good time to stock up while they’re $3 off. Our kids are big fans of the Smucker’s Uncrustables for their school lunches, so we might be stocking up on this while it’s $3 off.

In Alaska, Hawaii, Puerto Rico, and online the prices may vary by location. Not every item listed is available in all Costco locations. Items may also be available online for a delivered price. Which items stand out to you this week? Leave a comment and let us know!
