I just learned about this today, but I don’t instacart. But if you do, you can earn 1x Delta SkyMile per $1 spent if you link your Delta acct to your instacart acct. Don’t get tricked into trying instacart express if you don’t want it. You don’t have to click that. You can just link for the 1x mile per $1. But if you choose to do the instacart express or if u already have it, you get 1.5x miles per $1. Here is the site where u can link your Delta acct to your instacart acct. https://www.instacart.com/delta?
