There were a couple of items at Costco this week that I thought were fairly good.
One was a pack of three Coppertone sunscreen spray for $15. For us we need one for home and one for daycare at least, plus my DH burns easily and uses a lot. These cans are definitely more than $5 each in other stores.
Also, packs of 100 Tampax (regular or super) with a bonus of five Pearl were $12.79. Possibly not as good a deal as you'd get with coupons, but I find that for regular Tampax (not Pearl) there's not a lot of coupons out there. I must admit, I HATE the Pearl ones, they just don't work well for me. SDM has packs of 20 Tampax for $2.99, if you had $1 coupons that would be a better deal. But I don't.
We also bought a Roots backpack there today for $20. I bought two cheap backpacks recently for DS at Bentley. The first one the zipper went within a month, the second one, one of the straps and one of the zippers on a pocket failed about two weeks after he started using it. I should have brought them back, but DH had thrown them out. Anyhow, the Roots bags seem MUCH sturdier.
Six year olds are hard on backpacks, so it's not only that the bags were cheap, he dragged them around, etc. I've warned him that if this one gets abused and worn out this quickly, he'll be bringing a plastic bag to school with his belongings. :)
