Question: Is a 20 percent premium for delivery of Costco items a viable offer? Please discuss in comments.
Of the 15 items we sampled, in-store items were 19.7 percent cheaper than the same items on CostcoGrocery. (That number is calculated using the items’ full prices, excluding in-store-only discounts.)
