Actually don’t know why all the downvotes.
There are no mailers for ONE McMuffin at $2.50. If so, please show us coupon.
I think current coupons are 2 McMuffin for $5.00
Regular price ONE Egg McMuffin is $4.29, ONE Sausage and Egg McMuffin is $4.49, so OP’s post of a McMuffin for only $3.00 now is pretty hot.
