Where can I find fairly priced Sashimi fish?

Hello, fellow Houstonians. I've been on the hunt for some time around Houston trying to find sashimi fish at an affordable price. H-Mart, H-E-B, Daido, Seiwa, among other stores. They're all fresh and really tasty, however they are a bit on the expensive side as compared to eating poke at a restaurant which fetches the same price while getting more food out of it.

It doesn't have to be cut. The whole fish intact is fine as long as it is sashimi grade. Thank you for your help! <3
