I'm on my first pen which I got through Med Express. About to take dose 2 tonight so got a couple of weeks to work out what I'm doing. Do people stick to the same providers or do you swap about depending on cost? How would this work as for Med Express I had to do photo, photo ID etc. I'm not sure whether to stick to the one supplier or try and get the best deal going as this is such a push for me to be able to afford it. Just wondered what other people do.
