It depends on your area, what flowers you want, and if the flowers you want are in season. You're better off posting on your local board to get an idea of pricing in your area, but the cost very much depends on what your flower choices are.
It all depends upon the flowers choosing for your wedding. Also the quantity of flowers are required for the reception. Check the prices to florist as per requirement.
