Need advice about a flower contract

Hi ladies. I was just looking over my budget and all the contracts I have so far.

I've realized that I am not happy with what I'm getting from my florist.

I paid a $50 deposit via credit card and the florist sent a copy of the contract to me with the credit card receipt. As far as I can remember, I have not signed a copy of this contract.

-I was told on the phone that she would throw in extra rose petals. There is no mention of rose petals on the contract.
-I was only quoted for 12 tables, where I know I told her I guaranteed 150 guests. If I need more centerpieces, it would cost $75 per table. I want to have 13 maybe 14 tables in the contract.
-A throw away bouquet was also not in the contract.

What chance do I have of calling the florist and getting those things thrown in, after a contract was formed?

I am really unhappy about it all of a sudden. I'm wondering if I mention that I'm an LIWedding girl, if that'll help.....

Yes I cant see why you cant call and ask her to add those things that you would like to have them in writing.

Secondly, with my florist I dont finalize the # of tables until about 2 weeks before the wedding and I dont have to pay him until the day of. I left a deposit and thats it. I signed my contract but I went over EVERYTHING with him before HE would even LET me sign anything OR leave a deposit.

Did you see a sample centerpiece? Sample bok's?
