In my area, Kroger clerks ask us if we would like to round up to the next nearest dollar with the money going to the local regional food distribution center that services the area’s food banks.
Our Kroger does as well. Log in to your Kroger account and go to the left side of the screen under - My Account, you will see community rewards. Simply enroll in the program and designate your charity and it is automatically done with each purchase as long as you put in your Rewards Card information.
This is separate from any other program and you must enroll.
Also, Kroger has a prescription program that is $36 for the first person and $72 for up to 5 people or pets. I have scaled back my work insurance and save more money on the Kroger RX plan, plus you get Fuel Points (50 points minimum for each prescription you get filled. I paid .12 cents per gallon to fill up my truck last month. My total was less than $5.50
