We paid the traditional items for the Groom's family when our son got married. Flowers and the rehearsal dinner. $6,000 for flowers, $2,000 for the dinner. Dinner guests were more than just the traditional wedding party, but also their spouses and boyfriends/girlfrields and all out of town wedding guests, 30 people total.
I got off easy. The Wedding venue was $5,000, plus $80 per person for 75 people for dinner plus the open bar plus.....I don't want to know!
DD has already told us when she gets married, it will be small, it will be on a farm and my only expenses will be finger sandwiches and to rent two cows. She wants a cow at her wedding, and because cows get lonely, I'm going to have to rent two so they don't get lonely.
When DW and I got married, my MIL paid $500 for food and wine, and that was it. My mom paid for the rehearsal dinner, about $250 for our small group, and flowers which cost about $100 because the lady next door did flower arranging and her gift to us was doing the arranging, all my mom had to do was buy the actual flowers. My wife and I paid all other expenses. Oh, my mom did give us $2,500 towards our honeymoon.
