Wedding Gift Amount - How Much Money? From now on, $100 wedding gifts for all

I know gifts shouldn't "matter" in theory, but with all this etiquette and questions in the air I've decided to start giving a flat $100 per wedding gift :) That may be crazy (or weird), but with 4 weddings down it seems to be working so far!

We used to be hardcore fans of the whole registry phenomenon, but ever since getting married ourselves I realize just how nice getting cold hard cash is.
