How to control grocery delivery substitutions starts with clear choices in your Walmart account. You can set backup rules before your personal shopper selects your items.

You can keep your order closer to your plan when an item is unavailable. Your preferences can reduce random replacements and make each substitution easier to review.

How to control grocery delivery substitutions

You can compare substitution types before checkout and match each one to your needs. Your main options include no substitutions, best match, and a specific item replacement.

If you choose no substitutions, you can skip a replacement for that item entirely. If you choose best match, you can allow a similar item when your first choice is unavailable.

When you choose a specific item replacement, you can guide the order toward a product you already prefer. That option helps you control size, flavor, count, or package style.

• You can stop replacements with no substitutions.
• You can allow a similar option with best match.
• You can preselect a backup item for tighter control.
• You can update choices before shopping starts.
• You can reduce unwanted swaps by setting preferences early.

How do I communicate substitution preferences to my personal shopper?

You can communicate your substitution preferences through app notifications, SMS text, or saved settings. Those channels help you review replacements as your personal shopper selects your items.

If you enable app notifications, you can approve or reject a suggested replacement in real time. That option gives you a quick way to respond without opening every order detail screen.

You may also receive SMS text updates, which can make responses easier when you're away from the app. If you choose none, your saved settings can still guide the order.

You can get greater control when your notifications stay on and your backup items are already selected. That combination helps your personal shopper follow your preferences with fewer surprises.

Choosing substitution types and pricing policies

You should compare substitution type and pricing policy together because both affect your final order. A replacement decision can also change how charges or refunds appear for an unavailable item.

You may see pricing handled through a lower replacement price, a refunded difference, or no extra charge. Those policies explain how a substituted item is priced when the original item is unavailable.

If a replacement costs less, you can expect the lower price or a difference refunded back to your order total. If no extra charge applies, you can avoid paying above the original item's amount.

You can use these details to avoid confusion at checkout and after delivery. That clarity matters when you want close item matches without an unexpected price change.

How to choose good substitutions for grocery delivery

You can choose good substitutions for grocery delivery by comparing size, flavor, quantity, and package type. Those details help you avoid getting random stuff that does not fit your meal plan.

Look for a backup item with a similar ounce count, count size, or preparation style. You can keep your recipes on track when your replacement works the same way at home.

You should also check whether refrigerated, frozen, pantry, and produce items need different backup rules. A smart substitute for pasta sauce may not work the same way as a backup for fresh berries.

If you want tighter control, you can mark staple items with specific replacements and specialty items as no substitutions. That mix helps you stay flexible on basics and exact on harder-to-swap items.

Choosing fulfillment methods and out-of-stock outcomes

You can set expectations differently for delivery, curbside pickup, and shipping. Each fulfillment method can handle unavailable items in a slightly different way during order processing.

With delivery and curbside pickup, you may have more chances to review substitutions while your personal shopper selects your items. With shipping, you may focus more on receiving complete orders without replacements.

If you select do not substitute, you can have your unavailable item removed from that order instead of replaced. That choice works well when only the exact item fits your plan.

You can use no substitutions for brand-specific snacks, exact sizes, or specialty ingredients. You can use best match for everyday milk, bread, or other routine staples.

What to look for before you place your order

You should review your cart before checkout and check whether each item needs flexibility or precision. That quick pass can help you match substitution settings to how you actually cook and shop.

Consider specific replacements for recipe ingredients, lunchbox staples, and household basics you buy often. Consider no substitutions for trial items, gift items, or exact flavors you do not want to switch.

You can also check your notification settings so responses reach you during shopping. That step supports faster approvals and helps your personal shopper keep the order moving.

When you set substitution types, communication channels, pricing expectations, and fulfillment preferences together, you create a smoother grocery order. You can get clearer replacements, fewer surprises, and more confidence in every cart.
