Usually I think it’s more thoughtful to give people gifts that show you know them and care. I like to find something that’s not on their wishlist that I think they’ll like. But a wedding is different and it’s actually more thoughtful to give a meaningful amount of credits instead.
IMVU Weddings are dirt cheap compared to even the cheapest RL wedding. But there are still a lot of things that they need to pay for and get. It’s not always easy to put things on your wishlist and then wait for someone to get them. It’s very helpful to give them the credits to use for some of the things that come up. Also realize that sharing this type of emotion and special time is what this place is all about.
There are occasionally exceptions for some people that have lots of credits and this wouldn’t mean much. In this case, doing something special for them that takes time and shows you care, means the most. For example I made the wedding vow videos for Gabby and Kim as a special way to contribute.
