It works for me. Am I holding it wrong?

That's already beginning to happen: https://www.cheapism.com/costco-scan-and-go-technology/
> have a handheld scanner at each register
I've seen handheld scanners at each Costco register that I've ever paid attention to.
Their website/app makes it impossible to just see what’s in store at what price. Go search for coca cola and I see the price to have it delivered (much higher than in store) and a link to instacart. No pickup options or even prices.
On Sams Club’s website I can see that in store price and order it for pickup.
Again, Costco could keep the things we all like and just have basic 2018 functionality, it isn’t hard.
And maybe it's just their talented/experienced/numerous staff, but my in-store experience with their tech is as good as it gets. Stuff just works, and works quickly.
