Southwire 13055921 25 ft. 12/2 Gray Solid CU UF-B W/G Romex Wire – $15.29

This is 12/2 outdoor wire rated for 20A. 25ft worth for only $15. That is less than half the price of 25ft of 14/2 Romex, let alone 12/2.

You can use this indoors, it’s just harder to work with & strip. But the cost savings might make it worth it for an easy run.
