text: I hate those things too.  If I get one with an RSVP I'll return it declining the invitation.  If not, I just don't go.  If asked I'll simply say I'm not interested in the product or that I have other plans.  I don't get invited to many of these so-called parties anymore.\n\nFace it, if you lose friendships because you don't supplement their income then they weren't really friendships to start with.\n\nIf you feel bad about declining the invitations throw a dinner or cocktail party of your own where you don't expect people to spend money.  It works for me.
