[NSFW, possibly] How much does Cialis for daily use cost?

Like many men my age, I have ED problems. I also have BPH (benign prostate hyperplasia or enlarged prostate). I take Flomax to manage the pressure BPH puts on the urethra passing through it. But recent ads for Cialis for daily use note that it also helps treat the symptoms of BPH. I just wondered how much a month’s supply costs. Also, does anyone know how well it works, and how common the listed side effects are? I have a checkup scheduled March 9th, and would like to sort through whether to ask the doc about it or just let it slide. I do have prescription drug coverage, but if I suddenly add a costly new item, my carrier will bump my rate to recoup the cost.
