Courtesy of theknot.com: When dealing with wedding professionals (caterers, florists, etc.), be sure to clarify all the details and your expectations during the initial discussions. Make sure you get a contract specifically stating dates, times, and locations. Be sure to include what you feel is appropriate dress, and what you feel isn't. Spell out everything. Try to negotiate the best deal for goods and services, but don't sell yourself short on important things just to get a better price.Most importantly, be sure to read the fine print on every contract before you sign it, and make sure you're aware of cancellation policies and fees. Also ask if there's a grace period to cancel just in case you change your mind or something happens and you need to postpone the wedding (you never know).
