Just an additional comment on weddings and money-giving. As edel said, it is not at all unusual for money to be given to the newlyweds, especially by members of the family. You can always say, "we'd rather you spent it on something you really want".
In fact, "wedding lists" sometimes are really money lists in disguise, so even if there is a list, and you put yourself down for that fancy microwave oven...you may be giving money in the end.
