Retailers are all the same generic stuff. Lowes generally has the most variety. Shitty vinyl plank will break apart really easy because they have flimsy grooves. Most I've done has been fine though. There have been a couple times I got a box in and refused to continue to job with it. If they've got sample squares grab one and literally try bending the grooves and see if it has some play or if it breaks. As long as it's not complete trash it's all kind of the same.
