DEF sold at the pump is perfectly fine, and usually far less expensive than buying it pre-packaged. WalMart is - generally - one of the less expensive places to buy it, and it's still over $10 for 2.5 gallons. At the pump it's usually well under $3 gallon.
At one point we bought two of the containers from WalMart, and we refill them at truck stops as needed. That way we never risk running out even when many miles from a source.
The only issue that you might encounter is the need for a magnet to allow full flow at the pump. Some truck stops are equipped with dispensing handles with a safety interlock in the nozzle of the DEF pump - and some trucks have a magnet which encircles the inside of the hose inlet. If you find that you try to dispense DEF and it shuts off quickly (like a normal gas pump which shuts off when your tank is full), head to the desk and ask if they have a magnet you can borrow or buy. They will know what you mean. You first insert the nozzle through the magnet and then into the inlet on your truck.
I'd buy one and keep it in your truck. Not all truck stops use pumps that need a magnet, so you may or may not run into this. I know that some Loves locations such as Kingman, AZ need the magnet.
