I picked one up for $5.69.
The sweet King's Hawaiian bun also ups the sweetness level a little but is otherwise very nice with a dense, soft but sturdy cushion for the sandwich.
Overall, Arby's Brown Sugar Bacon BLT was just too sweet for me. I think I would have enjoyed it more with just one strip of brown sugar bacon or maybe even just all regular bacon with the King's Hawaiian bun (although I suppose they couldn't really call it a "brown sugar" sandwich at that point). Still, if you like a lot of sweet with your savory, you might want to give it a go as the quality is there.
