In defence of Fuizion, they have been trying to make very high quality meals using good ingredients. Good ingredients aren't cheap and the freeze-drying equipment is expensive (I believe they made quite an investment in kit). I don't know what their margins were, but on the basis of discussions I had with them regarding us possibly selling their meals I know there is not enough margin to support a sensible profit for both manufacturer and retailer at the prices charged. It costs more than you may think.
Of course, it's a separate discussion as to whether you want to pay £X for a freeze-dried meal (where X varies widely). Some do, some don't, it's a personal decision.
I'd be sorry if Fuizion have to close, they were trying to do things the right way.
