We have 8 on each side, so there was no way we could pay for them! I really don't think they would ever expect that we would anyway. I did go a bit overboard with their gifts because they are paying so much to come. FI bought all of the GM wedding attire as their gift. Also, I waited until I knew they were definitely able to come before asking them to be in the wedding and I tried to keep the cost of the dresses down as much as possible (and no matching shoes, jewelry, hair, etc.).
