In contrast to Best Buy or Target, the salespeople working at HH Gregg seem like they have been there forever and have a lot of knowledge of the product.
My first time in I was approached by two people and they quickly let me browse after I let them know I was "just looking". This is a pretty sparse store, not exactly warm and inviting, more like a warehouse.
But maybe that's how they keep the prices so low. I was looking at flat screen TV's and Dyson vacuum cleaners and the prices matched the specials I'd seen online. I'll be back to check 'em out again before I buy.
