Costco Catering Prices at a Glance
Costco does not post deli or bakery prices on its website, so these ranges come from member-reported warehouse price trackers, checked in October 2026. Prices vary by region and warehouse, and Costco Same-Day (Instacart) prices run higher than in-warehouse prices. Call your warehouse deli or check the Costco app before you order.

How to Order Costco Party Platters and Cakes
- Check the Costco app first. Costco is moving cake and deli-tray orders to its app and website during 2026, but not every warehouse has it yet.
- Or use the paper form. At the deli or bakery kiosk, fill in your name, phone, membership number, item and pickup date and time, then drop it in the order box.
- Order early. Allow at least 24 hours (48 hours for some cakes) and about a week before holidays and holiday weekends.
- Pick up and pay. Collect the order at the deli or bakery counter and pay at the register. A Costco membership is required.
- Need it today? Many warehouses keep a few ready-made platters in the deli case, but stock is not guaranteed.
How Much Costco Food to Buy for a Party
Platter serving counts assume a buffet with other food. If a platter is the main meal, plan on the low end of the range. These rough budgets use the October 2026 price ranges above.
| Guests | Suggested order | Rough cost |
|---|---|---|
| 20–25 | 1 sandwich platter, 1 fruit, meat & cheese platter, 1 half sheet cake | about $115–$120 |
| 40–50 | 2 sandwich platters, 1 shrimp platter, 1 fruit, meat & cheese platter, 1 veggie tray, 1 half sheet cake | about $235–$245 |
| 75–100 | 4 sandwich platters, 2 shrimp platters, 2 fruit, meat & cheese platters, 2 veggie trays, 2 half sheet cakes | about $470–$490 |
Good to Know Before You Order
- No hot catering. Costco does not deliver or set up, and it has no hot-food catering menu; the rotisserie chicken and take-and-bake pizza are bought on the day.
- Wing and sushi platters are regional or seasonal and may not be offered at your warehouse.
- Food safety: keep shrimp, meat and cheese platters cold until serving and do not leave them out for more than 2 hours (1 hour above 90°F).
- Cakes: pick the flavor, frosting color and a short message on the order form; designs are limited to the options the bakery offers.
- Other options: compare Walmart catering, Publix catering or Cracker Barrel catering for hot food.

Members can special-order party platters from the warehouse deli and sheet or round cakes from the bakery, then pick them up and pay at the warehouse. A Costco membership is required, and some warehouses also keep ready-made platters in the deli case.
How much are Costco party platters?
As of October 2026, member-reported prices put most Costco party platters at about $40 to $56. The shrimp platter is about $56, sandwich platters about $45 to $50 and the fruit, meat and cheese platter about $40. Prices vary by warehouse and region, so confirm with your local deli before ordering.
How much is a Costco half sheet cake?
A Costco half sheet cake in white or chocolate costs about $28 and serves about 48 people, based on prices checked in October 2026. It is a special-order item that needs at least 24 hours' notice. A 10-inch round cake serving 16 costs about $17 to $18.
How far in advance do I need to order Costco platters?
Order at least 24 hours ahead. Some cakes need 48 hours, and you should allow about a week before holidays and holiday weekends. If you need something the same day, check the deli case for ready-made platters, though stock is not guaranteed.
Can I order a Costco platter online?
