Rising for the first time since 2011, Costco will be raising annual membership fees between $5 to $10 starting on June 1, 2017. Specifically, the Gold Star membership and Business membership will increase from $55 to $60 and the Executive membership will rise from $110 to $120.

In addition to extra benefits with Costco Travel and Costco Services, the Executive membership provides a 2 percent cashback reward on qualified purchases. Basically, if you spend $3,000 in qualified purchases over the course of a year, you will regain the additional $60 spend on upgrading from Gold Star to Executive. The maximum annual reward earning in a single calendar year is capped at $1,000.

During 2017, Costco expects the fee increase will impact 35 million members. Comparatively, Sam’s Club (owned by Walmart) charges $100 for Sam’s Plus annual membership and $45 for the basic Sam’s Savings or Business membership. Sam’s Club has 660 locations in the United States compared to Costco’s 508 locations in the United States.

Neither warehouse chain has to contend with Jet.com anymore, an online retailer that attempted to bring the warehouse subscription model to the Web. Jet.com pivoted to a subscription free model before being acquired by Walmart last year.

However, warehouse chains still have to compete with Amazon. Amazon has continued to push into the warehouse chain model by offering Subscribe-and-Save bulk items for repeat orders as well as Prime Pantry, a bulk-order system for purchasing common household items such as food or cleaning supplies.
