You can buy groceries online from a mix of big services, specialty sites, and local-store apps, depending on what you care about most (price, speed, or selection).

Major “everything” platforms

These are usually the easiest starting point if you just want one place to shop.

  • Amazon Fresh / Amazon + Whole Foods: Fresh produce, pantry staples, and household items, plus access to Whole Foods’ 365 house brand in eligible areas.
  • Instacart: Delivers from many local chains (including regional supermarkets and warehouse clubs) so you can shop several stores through one app.
  • Shipt: Similar to Instacart, with same-day delivery from various local grocers and big-box retailers.

Think of these as “meta-grocery stores”: they sit on top of your local supermarkets and handle picking and delivery for you.

Big supermarket and retail chains

Most large chains now let you order directly through their own websites or apps.

  • Kroger and related banners (Ralphs, Fry’s, etc.): Order for delivery or curbside pickup directly from the chain rather than going through a third-party platform.
  • Regional supermarkets: Many mid-size chains plug into services like Instacart or run their own e‑commerce portals with click‑and‑collect.

These are good if you already have a loyalty card or care about getting the same weekly deals you’d see in store.

Specialty and “better for you” groceries

If you’re after organic, eco-conscious, or niche products, there are dedicated sites.

  • Thrive Market: Membership-based store focused on organic and natural brands, often at a discount vs. typical brick‑and‑mortar.
  • Imperfect Foods / Misfits Market: Focus on “imperfect” or surplus produce and staples to reduce food waste while saving money.
  • Vitacost: Strong on pantry goods, supplements, and health-oriented products delivered to your door.
  • Hive, Umami Cart, Weee!: Curated marketplaces for sustainable products or specific cuisines (for example, Asian groceries via Weee! or Umami Cart).

These can be ideal if your local store doesn’t stock the brands or international items you want.

Budget and pantry-heavy options

If you mainly need shelf-stable items and want to keep costs low:

  • Bulk and discount e‑stores: Some online retailers focus on non‑perishable pantry staples and cleaning supplies, often with bulk pricing and frequent digital coupons.
  • Waste‑reduction and surplus sites: Services similar to Misfits Market use rescued or overstock inventory to offer lower prices on certain categories.

You can also combine one of these with a local fresh‑food delivery service to cover produce and dairy.

Quick how‑to: ordering effectively

A simple, safe way to get started:

  1. Pick one main platform (for example, Amazon Fresh or Instacart) that operates in your area.
  1. Create an account and add your address to see which stores and services actually deliver to you.
  1. Build a saved list of your weekly staples to speed up future orders.
  1. Compare delivery fees, minimum order amounts, and substitution rules before you check out.
  1. Schedule delivery or pickup for a window when you’ll be home, especially if you’re buying chilled or frozen items.

A quick example: someone who wants mostly organic pantry goods might get dry staples from Thrive Market, then use Instacart for same‑day fresh produce and dairy from a nearby supermarket.

TL;DR: For “where to buy groceries online,” start with big hubs like Amazon Fresh, Instacart, or your local chain’s website, then add specialty sites like Thrive Market or Imperfect Foods if you need organic, eco‑friendly, or hard‑to‑find items.
