It's a much different service that Costplus

Costplus manufactures and sells drugs at a small markup over manufacturing cost.

TrumpRX appears to be more of a central clearinghouse where drug makers can offer discounts to consumers. And at least so far, they seem to be the same discounts that they already offer, when you look up a drug on the site, it redirects you to the manufacturer's website.

Maybe it's useful for people without insurance that don't know how to search look for discount programs to help them buy drugs and maybe some manufacturers will offer discounts on the site that aren't available otherwise, but it's not a competitor to Cuban's site.
