Here is my pre-wedding gift to all those newly engaged:
Marriage Partnership
Also for the wedding, I read somewhere if you go for "locally grown flowers" you get a great deal on prices...
And there are "stationery warehouses" that have 200 double envelope invitations that if you get what you want printed on there in the font that you want, they will do it for $100's less than the invitations stores cost. Like my mom did it for my "wedding" and it cost ~$50-$60 for 200 on a nice cardstock embossed invite with 2 envelopes...
