not fake, here's the specifics. 30 quantity of 20 mg. generic for Revatio manufactured by Greenstone. they sold me each of the last two months at $67.99. Now this month they want $500. Got no axe in WAG stock either way, don't care if it goes to $100 or $0. they would give me no explanation on the price increase, would not call the manufacturer. Basically said pay the $500 or take your business elsewhere because that is our price and we have no control over price. Even if it is a manufacturer price increase for a generic that WAG can't control, you'd think they would at least have a little intellectual or business curiosity about it. But no, just automatons filling prescriptions at whatever price comes up, no questions asked. If it was for me I wouldn't care so much, but i happen to be a dog lover and would like to see him live another year or two.
