My fiancé and I are paying for the tux rental for the groomsmen as their gift. Other than a thank you card should the groom give the guys something else at the rehearsal dinner? Each tux will set us back about $150.

Are you renting ties? If you wanted something more personal, you could supply their ties and gift them the ties as a remembrance of your wedding.

I think the gift you’ve given them is very generous. However, I would still give them a little something at the rehearsal. Are you crafty? Maybe like a beer stein with their initials (that could be like $3 each)? Or a bottle of their favorite alcohol? For something non-alcohol related, what about sunglasses, pocket knife, etc.?
