How we got these numbers

• Walmart+:Live observation from Apr 15 ($1.00)
• Amazon Fresh (Prime):Live observation from Apr 15 ($1.34)
• Instacart — Aldi:Category multiplier against Walmart base, adjusted for South Urban ($2.81)
• Instacart — Whole Foods:Category multiplier against Walmart base, adjusted for South Urban ($4.96)

Live observations come from public weekly ads (Aldi, Whole Foods) and BLS Average Retail Food Prices, refreshed daily. Estimates use a per-category multiplier calibrated to NPR, Consumer Reports, and Tasting Table grocery comparison studies.

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.

Houston grocery context

Houston is H-E-B country — most locals consider H-E-B the default for everything, and it doesn't partner with Instacart. That makes the 'best of the four major delivery services' question secondary in Houston compared to 'what does H-E-B not have that I need delivered?' Hurricane preparedness shapes how Houstonians shop: stocked pantries and bulk water are seasonal priorities June through November. Walmart+ stores are scattered across the metro from The Woodlands to Pearland, giving the broadest geographic coverage of the four services.

Use H-E-B for your regular shop and Walmart+ for items H-E-B doesn't carry well (specific national brands, household goods, electronics-adjacent items). Amazon Fresh is worth it for Prime members already paying $139/yr — at that point grocery delivery is essentially free above $100.
