I don't see old-gen airtags for sale on the website. Are they throwing them all out?

Apple rarely offers direct discounts of closeout or excess merchandise. Instead to clear out back stock they’ll work with partner retailers (Amazon, Best Buy, etc.) who don’t mind the brand perception associated with offering deeper discounts.

First-gen AirTags have been on sale on Amazon frequently over the last year, and they’ll probably drop the price again soon.
