This is one of the questions vendors are asked the most. While it is perfectly acceptable to inquire if there are any promotions or a discount available for your date, It is very beneficial for a prospective client to do their "Homework" , as mentioned before. know your vendor's product versus others in the field so you can make an informed decision for one of the most important days of your life and to be able to give a sincere compliment! Let your vendor know that you truly value their service and time, and then make your offer! You never know, the vendor you really want might be open to some negotiating.
