This is accurate. You need only to have a costco cash card to get the Costco price on the goods in store. That cash card does not need to encompass the entire price of the transaction, as your credit card can make up the rest.

I've heard this touted as a "hack" but this makes absolute economic sense for Costco -- they get an advance on your purchase and get you into the store to potentially see the value in signing up.

Oh, I absolutely intended to buy more than $25 of stuff each visit!

I just didn't imagine they'd let me say "Um, yeah, put $1 on my Costco Cash card, and the other $399 on my Visa".
