If the overall wedding budget stays more or less the same, increase of fees by other vendors (catering and clothing, for example) will squeeze the budget for floral decorations.
On top of that there will be more and more supermarket floral departments entering to the wedding business, not to mention the former florists now acting as home-based event florists. Both will create a downward price pressure.
Funerals, too, are a shrinking market. I blogged about it some time ago; take a look if you are interested "
Funeral directors want bailout."
Internet is a growth area and any florist who manages to capitalize in this market will out-compete.
In a larger city, it does make sense to use the Internet to capture random customers. In a smaller town (like ours), however, I think the reward would be greater if we focus on local clients. This is because in a small town, there just isn't enough random Internet traffic to capture.
Finally, I agree that every florist should at least give a serious though to selling "wholesale" flowers to the public (i.e., consumer bunches). Currently, this market is being served by supermarkets almost exclusively.
By allowing this to happen, local florists didn't just lose the sale of cash-and-carry businesses. They lost the face-to-face human contact with a large number of customers. This must be reversed if we have any chance for survival.
Just a random thought...
