Below are just a few of the things you can find at Walmart for just $4-$5 or less. There are so many items I could have included, but I try to keep it a rather short,targeted list of cheap items.
Do understand that prices can & do vary by store, even in the same city. Please feel free to comment with anything I may have missed.
