Yes, it could have been a glitch. All I know is (1) the muffin wasn’t available on MY app for purchase and (2) the store wasn’t OOS cause I bought one in store.
DDs are scarce in my area – the next DD is a good 20 miles away. So it’s not like I can easily go to another DD if I don’t like this one. (My DD charges $7.50 for the “$6 Meal Deal” . I guess they charge more because they can. The bagel sandwich was pretty good though.)
