Pure Orange Extract - 4 Ounce Bottle

Tired of the insipid orange flavoring that came with my Sodastream machine and reeling from the shock of the replacement cost I tried orange extract found in an upper level grocery store. It was only one ounce and on sale for $4, but it had the zip and superior flavor I was looking for. Still, I felt I could do better. Turning to Amazon I found that the bigger bottle and lower cost were indeed available. I would like an even larger bottle, such as the 8oz I found for the Blackberry extract, but this is still much better.
