Ammo near San Antonio

My son will be competing at the National Shooting complex next week and I am going to be there 3 days before he is. The prices for ammo (Winchester AA 1 1/8oz 1250fps 8’s and 7.5’s) are usually significsntly higher than we pay at dealers like Shydas or CAC). Does anyine have any local (within an hr drive of San Antonio) knowledge of any ammo suppliers thatbsell to the public for more reasonable pricing for 12 gauge target ammo? I will have a couple of days of “nothing to do”….so if ai can save some money and see another good ammo/gun store, it would be a fun side trip for me.
