Expired: Coupons.com app: Free hot dog buns, any brand up to $2.00 and can buy at many stores (see post for a list) - Item must be purchased by 11:59pm PST May 26th, 2020 and receipt must be submitted by 11:59pm PST May 28th, 2020
I bought a 16 pack of Kroger brand hot dog buns at Food4Less for $1.99.
There is a $0.25/1 Ball Park Buns when purchased at Walmart offer on Ibotta, so if you buy Ball Park buns you can get that extra 25 cents back, too. Evidently they cost $1.98 at Walmart, so you can make a 25 cent profit after Ibotta.
Thanks to MrsGuin for the tip.
