Why this category prices the way it does

Breakfast cereals and oats are aggressive loss-leaders for Walmart and Aldi — both carry private-label versions of every major brand at half the price.

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.
