The San Antonio grocery scene
San Antonio is H-E-B country in a way only Texans understand — H-E-B operates 70+ stores in the metro and considers SA a hometown market. Among the four major national delivery services we compare, Walmart+ has the broadest physical store footprint here, with stores in nearly every San Antonio neighborhood. Instacart has a thinner partner network in SA than in larger metros — Whole Foods is available, but Aldi has limited delivery range from its small handful of SA stores.
What we recommend for San Antonio
Walmart+ is the strongest of the four major delivery services in San Antonio — competitive selection, free delivery on $35+ for members, and South-region pricing runs 5% below US average.
San Antonio residents who want delivery beyond H-E-B should default to Walmart+ for any item Walmart sells. The annual $98 membership pays back within 25 orders. Use Amazon Fresh for Prime-eligible items you already get from Amazon retail.
South Urban pricing tends to run about 5% below the US average. That regional adjustment is built into the totals above.
Frequently asked in San Antonio
Why doesn't H-E-B partner with Instacart?
H-E-B runs its own first-party delivery and curbside pickup service through the H-E-B app. They consider it a competitive advantage to control the delivery experience end-to-end, so they've declined Instacart partnership offers. This makes H-E-B the only major Texas grocer not available via Instacart.

Walmart+ at about $48.73 for a standard basket is the most reliably-available cheapest national option in SA. Instacart-Aldi at $41.20 is cheaper where in range but Aldi's SA store count is small. South Texas regional pricing runs 5% below US average.
