When I stopped into my Price Chopper yesterday, I noticed they had M&Ms singles on sale 2/$1. There is a coupon you can print to save $0.50/2 M&Ms singles, which makes them cost just $0.25 each after the coupon!
M&Ms Singles, 2/$1 or $0.50 each
$0.50/2 M&Ms Singles printable coupon
Final Price: 2/$0.50 or $0.25 each!
Remember that sometimes prices differ from store to store, so you may or may not find this where you shop! However, it is always good to check if you plan on stopping on by anyhow!
