Purchased watch series 7 from Apple online Nov 26 2021 but never got $50 gift card

I was black friday shopping at apple online store and saw a promotion for $50 gift card for the purchase of the series 7 watch. I never got the gift card and called apple today and they are saying it was only for the series 3 or SE watch. I'm pretty sure that was not the case and now can not find the promotion anywhere. Why would they give you a gift card for $50 for buying a watch series that is several years old? this doesn't make sense.
