What you expect.
My nephew and I were looking to purchase a few small table top Christmas trees to place throughout our home. I usually never shop at Big Lots, it's just not one of the stores I usually purchase anything from. However, Big Lots stores carry a great selection of item. You can find amazing seasonal items at affordable prices.
The only drawback would be that Big Lots doesn't carry large quantities of items and the staff can be less than enthusiastic about helping you find what you're looking for.
With all that being said Big Lots is kind of what you expect, out of your shopping experience.
