Instacart complaint: Rip off!

I purchased a bag of Utz Potato Chips. On the bag it states $4.29, yet Insta Cart charges me $5.29. I spoke to the manager numerous times about the prices and he told me the store prices are honored once they go through checkout. This is not the case, as I spoke to Insta Cart and they told me the prices on their site are the prices charged. The ONLY time you get a reduced price is with your first order. This is clearly a rip-off! Not only that, but since my first order, Insta Cart no longer puts your receipt in the bagbox. On my first order weeks ago, my receipt showed the in-store sale prices, yet my Insta Cart receipt showed the sites prices. Add on top of that, if they put your order in bags, even when I specify boxes, I get charged for those bags. Also, I buy Boar’s Head Gruyere cheese. In store it’s $5.99, on Insta Cart it’s $9.19!! So Insta Cart is not only making money on marking UP prices, but they charge you for delivery, a tip and another fee for delivery. They are CLEARLY TAKING ADVANTAGE OF PEOPLE!!
