I thought it was strange that they swapped one dish soap brand I chose (at Costco) for another, the other being twice the price. The dish soap I chose was NOT out of stock at Costco. Lots of other comments say something similar - that more expensive items were swapped w/o reason. I hadn't heard of Instacart... was given a gift certificate which I used to get cleaning, personal, pet, and paper goods. I prefer to get my own food items. Instacart can be convenient to use on occasion - if you have a broken arm/leg or the flu. I wouldn't write them off completely, but (in my opinion) it's not cost effective for the average person who can drive to the store and do their own grocery shopping. The only thing saved is time.
