It depends how you look at it!
Im on the boots scheme and paying £90 for 3 months, so £30 a month and I get propecia, don't get me wrong I know you can get proscar alot cheaper but its the support im getting, and quarterly monthly photos which they give me and checkups, I plan to follow this for a year then perhaps go it alone!
Its been good for me so for that reason im happy with the cost, but I appreciate everyone situation is different!
