I looked all over for this stuff. I finally found it in one very chi chi upscale grocery store, which means $$$. I used it in my iced coffees and in desserts. it tasted fine but the bottle got used up way too fast.
I use Sugar Free Torani Chocolate Syrup and it works ok for me and also is less expensive. If the cost of the extract isn't an issue for you, it might work out well. I just know I tend to glug the stuff into things and the bottle was gone in the blink of an eye.
