If it were me, I'd get something small as a token of congrats. Maybe a gift card to treat them out to something. If he's one of your buddies at work but you guys don't really hang out beyond that, I wouldn't spend more than around $20 or so. Just a simple small little gift.Question for you lads. My co-worker is getting married soon. Good dude, we work together a lot. I've met the fiance once in passing. Would it be polite/expected of me to buy them a gift? We don't really hang out outside of work and I'm not invited to the wedding or anything. What say you guys?
