Reese's Big Cup with Nuts - Limited Edition

This was good. It's a big ol' fat Reese's Peanut Butter Cup with chunks of peanuts. What's not to like?
The only drawback is it's sold as a single cup. These monsters should be sold in the twin pack. Obviously, it's going to be marketed as an impulse item by the cash register at the late night convenience store nearest you.
Hershey's Nut Lovers - Limited Edition

Hershey's chocolate bar along with almonds, cashews, peanut and pecan
pieces. Ignore the picture of whole nuts on the wrapper that is meant to mislead you.
As for taste, imagine a Mr. Goodbar but kicked up a notch. It's nutty in every bite.
The drawback is, as the label points out, it's pieces of nuts. It'd be great if you could get a better taste of the individual nut flavors but you don't because it's just pieces. However, I think the "nutty-in-every-bite" tilts this candy bar towards a "thumbs up" from me.
Another caveat is that it is a smaller bar than the regular Hershey Chocolate Bar. Where the regular Hershey bar has 4 columns of three rectangles, this bar is 3 columns of three rectangles. I suppose because it does contain a lot of nuts that they could justify the smaller bar for the "regular" price.
