We have had TF, FTD, Carik, Red Book, and more. We were wire service free for several years, unless you count IFA as a WS.
A few months ago, after much deliberation and soul searching, and on the reading of some FCers' comments and talking with another florist friend who even showed me how he was making money, I decided to try Bloomnet.
Another thing which prompted the decision was that I had purchased a building, and the economy promptly went south, taking my largest tenant out also. Local orders had suffered from the move to the new location (there is a thread here which states that relocating a shop will cause that shop to lose 25%+/- in business and will take 3 years to recover.
I have actually been surprised that I'm not unhappy with Bloomnet. We get lots of orders from them, and if we need more $ to fill the order, they send it or they cancel. Either way is fine with me because I'm not going to fill an order on which we do not make money.
We seldom buy a container from them, and when we do, it's on sale. There are other reasons that we are staying with Bloomnet for now. I make no apologies for doing what is best for my shop and my employees.
I was a huge cheerleader for being WS free, but right now, Bloomnet is working for us. I am certainly no cheerleader for them, but, for now anyway, we will probably stay with them for a while.
