Need help with live feeders in East Dallas

I am having some serious issues with getting live feeder rats reliably and at a reasonable price. I have been having absolutely zero success with Pet Snake Snacks and Big Cheese is far enough away that it would be cheaper buying from a few of the pet stores that offer something besides basic rats. I'm looking for other owners who may be interested in either going in on a weekly group order with big cheese or anyone who can get me on Pet Snake Snack's radar.

I have talked with Otis at PSS(Pet Snake Snacks) and have tried repeatedly to even drive there and pick up but he never calls back and no one ever seems to be there. I'm really in a desperate situation.
