Zero cloud trust and yubico-promotion - offer claimed?

Hi, I was offered Yubico Key under zero trust and whenever I click I was presented with “Offer Claimed”, I never claimed any offer so far and I’m interested in getting Yubico key on discounted price.

I’d like to know if how and when did I claim this offer. Thank you
