I love Big Lots. They have really good prices, and an amazing array of items that are overstock from other, higher-priced stores. I have found everything from Christmas lights and ornaments to camping equipment, clothes and home decor.
The people at Big Lots are usually very busy, so be prepared to browse the store by yourself. That's okay, though, since it's really easy to find most of what you might want.
Be prepared to be surprised, be prepared for bargains. The selection changes frequently, and when things are sold out they probably won't be back, so grab it when you see it!
