I bought 5 pairs of chinos at Costco all the same band and marked as the same size. Had to take 3 back one was to big in the waist and length one was to short in length and one was to small in the waist. 2 from Red China and one from Red Vietnam.
The problem with buying clothes at Costco is, you can’t try them on and have to drive across town to take things back.
Been buying the same Gloria Vanderbilt jeans there for a decade. Don’t have a membership, but friends can pick them up for me. Plus frozen salmon patties and frozen organic blueberries. Occasionally King Crab legs, fresh from Alaska, better than lobster.
Conceivably, if Amazon product managers have their wits about them, they can compete with Costco. Big plus, delivery and no parking problems.
