Here in TN we have a few Farmer supply stores call Co-Op, they usually have a good variety of fencing from 1/4 x 1/4 inch up to pig wire. If you do not have store like that, then check TS online store and I bet it can be ordered. We have a TS as well but they do not carry in stock most of the items that the Coop does, but TS always says they can check and see if they can order it, when I need it yesterday!
TS online store is better and I believe you can have items shipped to your house during order.
Co-Op- online store is bad, and I think you have to call and order (old school) but then again everything I have ever needed was there.
Other alternatives- If you cant find what you need at either and need it "yesterday", you might consider calling some fencing companies, but I am sure the fence will cost more as most are private, independent, commercial or custom contractors.
