Why this category prices the way it does

Produce pricing swings with season and source — Aldi and Whole Foods source different supply chains, so the per-pound number on a given week can shift more than other categories.

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.
