What happened?
Modern Retail reported on September 24 that Costco’s digital sales are expected to reach about $33 billion in 2026 and maintain growth of more than 20%. Growth drivers include its website, ecommerce partnerships, and connections with instant-delivery platforms such as DoorDash and Uber Eats. This is not a direct rule change for Amazon or Walmart sellers, but it can offer a reference for cross-border product selection and channel strategy. Consumers are increasingly willing to buy online everyday goods, household products, food, health products, and frequently replenished items that previously depended on physical stores, while placing greater importance on member pricing, delivery convenience, and brand credibility. Cross-border sellers operating in the U.S. market can consider large packs, multipacks, refill products, and household stock-up products, but need to assess storage volume, shelf life, food or cosmetics compliance, and last-mile delivery costs.
What does this mean for cross-border sellers?
Costco’s digital sales are expected to reach about $33 billion in 2026 and maintain growth of more than 20%, indicating stronger online purchase interest in everyday goods, household products, food, health products, and frequently replenished items among U.S. consumers. Cross-border sellers can consider large packs, multipacks, and refill products, but must also calculate storage volume, shelf life, food or cosmetics compliance, and last-mile delivery costs.
What should sellers do now?
- 1Use product-selection tools to screen everyday goods, household products, food, health products, and replenishment listings for the U.S. market; record package volume, shelf life, and compliance requirements, then produce a candidate list and remove products with incomplete information.My AI Agents
- 2Measure the length, width, height, and weight of large-pack, multipack, and refill products one by one; calculate the impact on delivery billing, flag oversized SKUs, and create a product table covering dimensions, weight, and logistics assessment.Dimensional weight
- 3Enter procurement costs, selling prices, warehousing costs, and last-mile delivery fees into a profit calculation; review the profit results for priority household stock-up SKUs and produce a decision list for keeping, repricing, or pausing listings.Profit calculator
