If you want a lot, then trans shipping them is cheapest. There is no guarantee that you will get anything nice or unique.
Land them in their own tank so that you don't have to dip them until they are more established. These were under the sun a few days ago, so I like to land them under 6500k Halide. Once they are growing and healthy, then I will dip them if I need to.
If you just want a few, then LiveAquaria, Unique or others often have some. You can bet that they will keep anything that in new or unique looking... so the stuff that they offer for sale can be nice, but not outstanding.
Some LFS call the AquaCultured stuff wild - they are not. If they are on a base, then they are not wild.
