Most Gps have stopped prescribing strips for nn-insulin users. that's why most of the meter suppliers now provide an excellent service selling consumables. Abbott, who supply the Freestyle meter I use sell direct for £16:?? and no extra charge for P&P which is by first class post. They keep a data base of custmers. I imagine the other suppliers do something similar.
If you want to buy your own, xheck with your meter supplier.
The Code Free meter I bought from Amazon has very cheap consumables, but I found it unreliable and have sent it back. they did admit there had been some "issues".
