Thanks for your replies.
Decided to use the new Lite machine and get a spare one (currently £6.50 at Boots). Have taken the prescription change slip to the surgery. I will indeed offer the two unused Minis for rehoming - but in view of previous pattern that when I change machines they put me back to 1 pack of strips and the wrong lancets, and I end up having to make (waste) an appointment with my doctor to get it sorted, I'll wait till I get the new prescription Friday evening before making them available. Depending how long this takes to sort, some Mini strips may be going spare too, along with cases, fingerprickers etc. (Don't you just hate that drawer full of assorted stuff you no longer need but will just be destroyed if you return it to the chemist?)
Will post an update over the weekend.
