I had tried one substitute that was posted here a while back...I can't remember what it was, but it was sold at Walmart. But I don't think that there's anything as tasty as the Jet Starts. They really are yummy.
I usually sub the starbuck bottled frapps light if I can find them, but I like the jet starts better. The regular have about 40-60 calories more than the jet starts. They must be having problems getting them all over. Our COD has been out for almost 3 weeks and doesn't know when they will come back in. My think lately is a Starbucks venti iced americano with about 4 oz. skim milk added. That keeps me going all afternoon.
My center has been out for about two months & they are saying that it will still probably be another month!
I talked to one of the counselors today & she said that one of the other local centers got some in the other day & it was missing the coffee flavoring & was just the cream. She said apparently there are some major issues with the manufacturer. I've about given up on them after being deprived for 2 months.
