How much Lantus do you use? In Poland I was paying around $100 for 5 pens, in UK not much more (without insurance). Test strips (Accu-Chek) arround $15 for 50.
I use 20 units daily. I believe the units are 1/5 mL each. That's definitely a better price than I can get here—although I did just find out I can do the old jar/syringe thing for $267! Ugh.
