If you shop at Costco, brace for higher membership fees.

Starting in June, the wholesale retailer announced on Thursday will increase its annual membership fees by $5 for U.S. and Canada Goldstar (individual), Business, and Business add-on members (“Primary” Members). That brings the total annual fee to $60.

Annual executive memberships fees in the U.S. and Canada will increase from $110 to $120. The maximum annual 2% reward associated with the Executive Membership will increase from $750 to $1,000.

The rate hike affects around 35 million members, about half of whom are Executive Members, says the company.
