Need to buy rays

Going shark fishing. Can anyone tell me where I can buy rays in or around Galveston? Short trip so I don't have time to fish for bait. I normally fish PINS so I don't know a lot about the Galveston area.

This was the only one I could find that had a legit website and listed stingray. Most don't have any, but you can call to confirm what bait they have. I just Googled Galveston Bait Shops.

You could check on some of the seafood places by the Kemah Bridge. Clear Lake Channel Entrance area.
