I'm sure someone has mentioned this but I found Torani SF syrups at COST PLUS, and they were the BIG bottles (25.4 FL) for $5.99 each. They are sweetened with Splenda. WOOHOO!
Off the top of my head these were the SF varieties that I saw:
Lime
Orange
Vanilla
Raspberry
Chocolate
Almond
Peach
English Toffee
Irish Creme
Almond Roca
Cocconut
Aaaagh! That is all I can remember right now. I used a dab of SF ...
