I think the key is in this sentence from the press release:
"The products will feature Jamba’s signature recipes, and they will be the first smoothie kits in the marketplace to include vitamin and mineral boosts."
If they price them fairly, this may be a good deal. It is true that you can simply purchase the required raw ingredients and make smoothies yourself. I do it all the time, in fact I have basically reverse-engineered the Chunky Strawberry and make it for myself for breakfast quite often. However, even the ingredients are not cheap (I buy bags of Trader Joes' frozen strawberries, for example).
If JMBA packages them per their recipes, includes a proprietary boost, and keeps the price reasonable, they may have a winner.
agree. Its all about simplicity. People will buy it and make it at home. I've bought some of the kits that Target has. They are ok. Just basically frozen fruit. If JMBA can improve on it and make it taste close to the fresh made then they'll have a winner.
