What would you do in this gift-giving situation?

My brother and I have been giving each other a $50 Target gift card on our birthdays, for the last several years.

While he’s actually been buying my card at Target, all I’ve been doing is regifting the same card to him on his bday.

However, last December he gave me a card for $70, when I turned 70.

He’ll be 67 this July 14. Should I give him a card for $67, or wait until he’s 70, and then give him a $70 card?

Ultimately, I’d like to terminate the card exchanging. Hypothetically, if he agrees to that, do you think should I give him a $70 card on his 67th?

If I do propose that we end the card exchange, I won’t be suggesting that we end our birthday celebrations entirely. To me, the primary reason for the celebrations, is to hang out and treat the honoree to a scarfathon at an eatery of their choice.
