I have no doubt that this has been asked before, but me and DP have a wedding this weekend. The couple are friends of mine from our University days (closer to the Bride than the Groom) who I haven't seen for a few years. We have only been invited to the evening do and I was wondering how much cash I should put in their card? The couple are in their 20s and have been living together a while so they have pretty much everything they need.
