I usually shop at my nearby best market. When I saw in their ad they partnered with instacart i figured I would try delivery. Ordered 15 items, respond was 9 items unavailable. Then, that I had insuficent funds. I knew there was enough to cover my order so I called instacart. They need to take more than authorized to cover replacement items. I hadn't gotten a message of what replacements were made, because they hadn't done that yet. They actually had overdrawn my account but I have that protection no harm. I told them to cancel the order and return the charge I did not authorize. They said 24 to 48 hours. I said supervisor aand fraud and got my money back right away. Got in my car went to my best market which they said they were shopping at and everything was in stock! My guess is they don't like sale items and half my items were from the weekly ad. Wasted too much time and effort.
