Sapphire Preferred: You'll earn 3 points for each $1 spent on purchases in the following rewards categories: dining at restaurants including takeout and eligible delivery services; select streaming services; online grocery (excluding TargetŪ, WalmartŪ and wholesale clubs).
With the coming end of Q1/Q2 bonuses at grocery stores and Whole Foods, I tested a couple of ways to get groceries to code at the 3x on CSP.
Kroger - Kroger Pay (scan to pay in app) codes as 3x
Whole Foods - Palm payment codes as 3x. Order pickup through Amazon app also codes as 3x.
That covers a majority of our grocery spend. I could not figure out a way to pay with the Safeway app to try at that chain.
