Instacart complaint: Pricing Policies

I was using Instacart for several months and thought their service was good and the shoppers tried very hard to fulfill the orders. However, last week I placed an order and asked the shopper for a copy of the paper receipt from the store, not just the e-receipt you receive after delivery. To my shock and utter dismay the paper store receipt showed a total due of $101.80 which was paid using a debit card, the e-receipt showed a subtotal of $140.12 (before taxes and other charges are added). That’s a difference of $38.32 from what the actual cost of the groceries were to what I was charged by Instacart. When I tried to contact Instacart I kept being referred back to read their Pricing Policies which I did several times. But, that did not change what was actually paid to the store $101.80, and what I was charged $140.12. Instacart tries to hide this mark up by increasing the prices of the items you purchase. DON’T TRUST THEM AS THIS IS A BLATANT RIP OFF they try to blame the store for, but it’s actually Instacart raising the prices for more profit.
