CONGRATS!!!!!
Depends on what you want...do you want the big everything?! Or are you keeping it simple?

We saved on:
-finding a venue that we could take our pictures at, and they included: our meal, everything needed for dinner - chairs, tables, linens, cutlery, etc.
-not having a limo and getting nice rental cars
-making our own bouquets - with fake flowers (bought at Michael's with 40% off coupons)
-again from Michael's, using coupons...bought the invitations and did them ourselves
-no videographer (sp)

One thing to splurge on is finding an amazing photographer. It's well worth the money - believe me, cause we didn't....

PM me if you have any questions, or need help! I love planning our wedding. Everything was done a month prior to our wedding so that I wouldn't stress.
