not every product is cheaper... i have to visit Sam's Club and Amazon for various items that are no longer at Costco or more expensive at Costco over the past 2-3 years...

​

like this product -- I got 4 boxes ($28 per box) from Amazon 3-4 weeks ago -- comparing to Costco- $33+ shipping? Costco can not beat Amazon when it comes to shipping or product price sometime.
