1.
A Big-Box Store is a large, free standing rectangular single floor store built on a concrete slab. They are incredibly wasteful and ugly to look at having no aesthetic value what so ever. Typically have very large parking lots with no trees.

Also sometimes called a superstore, megastore, or supercenter.
Walmart is a good example of a big-box store.

2.
Large, high-volume stores. I.e., Circuit City, IKEA, Target, Home Depot, Best Buy, etc.

3.
A large department store modeling the architectural design of a warehouse. These are usually built in the suburbs where land is much cheaper than downtown.

So named because they resemble shipping giant boxes plopped in the middle of a sea of parking.
Big Lots, Target, Best Buy, Circuit City (RIP), and Bed, Bath & Beyond.

The King of Big Box Stores: Walmart.

4.
A large store (superstore) run by a major corporation.

No one knows where the term came from (Because the store's goods are shipped in big boxes? Because the store looks like a big box?) As a result, anyone using the term should be slapped with a large trout for using a phrase which they themselves don't really understand.
In today's financial news, big box store Target is increasing its competition against big box store WalMart. Ow, that trout hurt!
