There are a few items that a budget bride needs to spend money on! The information and peace of mind is worth it.
The best budget bride book is called Bridal Bargains: Secrets to Throwing a Fantastic Wedding on a Realistic Budget. It retails for $14.95, but you can often find it at Amazon for less or you can purchase a used copy. Try to get the latest version or one previous (any earlier than that and you run the risk of getting outdated information).
Every bride also needs an organizer. You can print out the information on budgets and purchase a few manila folders to make one yourself or you can buy one. It is easier to keep track of budgets, timelines, and offers if you put everything in one location. The The Ultimate Wedding Planning Kit: From America’s Top Wedding Experts, Elizabeth & Alex Lluch is amazing! It is very comprehensive. Organizational methods are personal though so make sure you find one that works for you.
My final recommendation is a book for your new life together. It is called Get Financially Naked: How to Talk Money with Your Honey and it is an excellent read for couples. It is easy to briefly put the marriage topics aside while you are planning a wedding, but many topics (such as kids and money) are much easier to handle if they are discussed before.
