The instacart has unfair rating system, which means that customer is always rite and shoppers are nor protected from unreasonable bad ratings. Second of all, recently it came up with a new idea of prioritizing new shoppers, which means even if you worked hard and have a good ratings, you wouldn't be able to see any good orders. Thirdly I have noticed on many occasions that shoppers are not paid for heavy pay. It says that heavy pay included, when you can see that the batch pay is still $7.
