No matter where you buy lumber, you need to sight along the length to make sure it is not warped. Then if it is "green" lumber, store it out of the rain and damp if possible, to avoid warping at your place. The cheap lumber is usually green, but you can get good stuff if you are careful about sorting through it. Some customers leave the sorted bad lumber just laying around in the aisle so some stores are starting to get annoyed when you sort through the stacks. I never have any trouble, but I make sure to replace all the unwanted pieces. LOL
