I know technically there's no such thing as "generic" Viagra, but if you google it, you see a lot of Sidenafil Citrate pills, which is the active ingredient in Viagra.
Not that I need it of course...

I might want to get an affiliate account. But in case I might, you know theoretically need it at some point, is there a certain brand, type, or online place to get it without getting screwed?
