I ran the numbers a couple months ago. They added roughly (on average) 20% to in-store Safeway prices, in addition to charging for delivery. I noticed at the time that they were scraping everything off Safeway.com's listings. Safeway.com prices themselves had a certain % markup on top of in-store prices, and Instacart had added its own markup to the Safeway.com prices. Things may have changed since then. I expect prices to fall as they scale.
