I bought one for $4.45.
True to the name, the bacon was very smoky with a delicious, porky flavor that wasn't too salty, as far as bacon goes. Unfortunately, it wasn't crispy at all and, despite appearances, was pretty soft all around.
The croissant was very buttery with a decent flakiness. It crisped up very nicely out of the toaster oven (as breads are wont to do). It was a little dense though.
