Don't bother setting a spending limit before you enter Big Lots. If you do, you'll only end up finding a spectacular deal on something that you really want and/or need. So, you'll end up disappointing yourself by spending more than you intended or by missing a great deal which probably won't be there the next time you decide to visit.
This is a nice Big Lots with lots of cool items and ever-changing deals. Even though the exterior looks ancient, the interior is clean and the staff is courteous.
