I pledge to learn how my benefits support my physical, emotional, financial and social well-being in 2026.

I’ll explore ways to use them to improve my health, reduce stress, manage my money and so much more.

Get to know your benefits with monthly WITT emails and texts.

Understand your benefits with informative videos, articles and podcasts featuring Costco employees.

Use your benefits with the help of WITTpledge.com and your 2026 Benefits Guide.
