Just to let you know that I went to a local independent pharmacy in my town who used the phone number / PIP code given out by Paul the other day and they have secured 8 boxes of the Zentiva brand which were delivered the next day - no problem!
Shame on Boots - a large pharmacy chain who can no longer supply the specific brand I require as they only deal with Alliance distributers. What happened to the individual and the personal touch? They have gone down in my estimation.
Thanks to Paul for his time and effort in clarifying the situation for me.
