Why this category prices the way it does
Meat is the highest-variance category by retailer — Walmart's in-house meat program runs ~30% cheaper than Whole Foods' grass-fed/organic-leaning case for comparable cuts.
San Antonio grocery context
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.
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.

Service fees, delivery, and tip all depend on basket size — the cheapest per-item service isn't always the cheapest overall.
