It goes for $3.99 but I received this one courtesy of Wendy's.
They've gone back to the foil wrapper of old (maybe for a touch of nostalgia):
In case you're wondering, the Dave's Single is mostly the same as the previous Hot 'N Juicy Single Cheeseburger (you can check out my previous review here). The only difference is the bun and new mayo.
