Beyond+ Membership – $29 bonus card with enrollment

Bed Bath & Beyond is offering a deal where if you sign up for its Beyond+ membership, which costs $29, you get a bonus card for $29. https://www.bedbathandbeyond.com/…beyondplus
I thought I saw somewhere that the bonus card must be redeemed within 15 days, but I refreshed the page and don’t see it anymore.
