$3 per tab domestic. Less if you buy liquidex (but have to buy a whole 80mg) or from an overseas source but then you have WU fee's, more expensive shipping, a longer wait and a chance of seizure.
You can get them as low as $2.50 per generic 1mg tab (domestic) if you know where to look......I've seen them as high as $9.00 though (it's rediculous how some sources try to rape people).
