Most sealed condiment packets are made for pantry storage, but it’s always smart to follow the instructions printed on each packet.

• Before use: Keep packets in a cool, dry place away from heat and direct sunlight. A cabinet or pantry works well.
• On the go: For lunch boxes or picnics, an insulated bag with a cold pack can help maintain quality, especially in warm weather.
• After opening: These are single-serve, so use the entire packet at once and discard any leftovers.
• When in doubt: Check the best-by date and any storage guidance on the packaging.

You can shop a wide selection of single-serve mayonnaise packets on Walmart.com and, in some locations, in stores.

• Online: Search for terms like “mayonnaise packets,” “single-serve mayo,” or “portion control.” Use filters to narrow by pack count and fulfillment (shipping, pickup, or delivery where available).
• In store: Availability varies by location. Check the condiments aisle or ask a store associate.
• Tip: Use the “Check availability” feature on the product page to see if your local store carries a specific item before you visit.

Walmart carries a range of single-serve mayonnaise options to fit different needs.

• Packet size: Common single-serve packets are around 9–12 grams (about 0.32–0.42 oz), suitable for a sandwich or small salad.
• Pack counts: Choices typically include small multi-packs for home use and larger cases for offices, events, or foodservice—ranging from a few dozen to several hundred.
• Formats: Look for easy-open stick packs and tear-open pouches designed for quick, mess-reduced use.
• Fulfillment: Many options are available for shipping, with select items eligible for pickup or delivery in some areas.

If you’re watching spend, there are a few ways to shop smart on Walmart.com.

• Right-size your order: Try a smaller pack to test, or choose larger case packs for events when you know you’ll use them.
• Compare counts: Sort by pack size and read descriptions to find the best match for your usage.
• Check promotions: Look for online deals or seasonal promotions that may apply to pantry staples.
• Plan fulfillment: Pickup or delivery (where available) can save a trip and help you stick to your list.

Policies around free condiments vary by venue, so purchasing the quantity you need is a reliable approach.

It depends on how you’ll use them, but a quick guide can help.

• Lunches at home: Plan about 1 packet per sandwich; keep a small multi-pack in the pantry for convenience.
• Office break rooms: Medium cases provide steady supply without overstocking; consider how many people regularly use them.
• Parties or catering: For buffet or sandwich bars, estimate 1–2 packets per guest, adjusting for preferences and other condiments.
• Tip: If you’re unsure, start with a moderate count and track usage, then scale up or down on your next order.
