Wedding Card Map Program Is All Of This Stationary Needed?

Is all of this stationary needed? - wedding card map program

So I have a list of wedding stationary, but is it really necessary? I'm trying to save money for my wedding, but I think it's several hundred dollars off. Some of them do not even know what it is! Please take a look to see whether there is anything I can do and I know that my guests will be offended that (which I do not know b / c I've never been to a wedding). A million thank you!
