From Lowes would be Pro mix Hp, Greensmix steer manure, chicken manure, mushroom compost. Kellogg's soil conditioner ( fine wood chips). I was buying perlite there but Napa auto parts sells diatomaceous earth (floor dry) for less and it does not float to the surface

. I also buy a bottle of fish poop 5.1.1 although I really hardly use it.
Other than those things I go to a garden/pet store for my dry amendments like Kelp meal, Alfalfa meal, Crab shell meal, Azomite, Langbeinite, Humic acid, Green sand, Oyster shell..........
