When I played my Wishmasters, my two sims started out as boyfriends and got married about halfway through, right before they had kids but after the one working spouse had climbed the music career ladder and so had made friends with a lot of very ritzy celebrities. I don't think there was a single gift under 10k simoleons, and they got at least five, including a car and a hot tub. I'm not sure if celebrity level of the giver has anything to do with the cost of the gift, but hey, it's worth it, especially if all you need to do is "chat with co-workers" for a little bit every day while working. I loved that my sims were getting wedding presents, but none of the givers had been invited to the wedding.
As for IFs, none of the six children in that challenge got one, but on my first attempt (which got fried by lightning) both of the children I'd had when I had to stop received them.
