I got a full packer brisket delivered from Costco. The delivery agent was polite and friendly.
After he left I checked the receipt and noticed that I had been charged more for my item than I should have been.
I called Instacart customer service and explained the problem. Instacart adjusted the weight of the item from the ~8lbs to the to the actual weight of 15.05lbs.
They did not however update the $4.39 price per pound to the actual price which is $3.49 per pound at the Seattle area Costcos. They refused to adjust the price to reflect the sticker, which is outrageous, because they only go by their catalog prices.
Caveat Emptor - buying anything by the pound from Instacart will likely surreptitiously overcharge you.
Reason of review: Pricing issue.
Monetary Loss: $14.
Preferred solution: Let the company propose a solution.
