The daily-dosing arithmetic

Daily low-dose tadalafil looks more expensive than on-demand because you buy thirty tablets a month instead of four. In practice the gap is much smaller than expected, because the daily tablets are 2.5 mg or 5 mg while on-demand tablets are 10 mg or 20 mg — and generic pricing is largely per tablet rather than per milligram.
