I raised this issue a couple of years ago in this thread. I previously used Instacart for grocery delivery, mostly from Safeway. But since I discovered Instacart’s practice of marking up prices, I’ve stopped using Instacart and just shop directly on the Safeway web site. As far as I can tell, they don’t mark up over in-store prices, and with a FreshPass membership, delivery is free. FreshPass costs $99/year, but gives you a $5/month credit, so if you use it every month it’s really $39/year, which is totally worth it. All you pay above going to the store and shopping yourself is the driver tip.
