After several hours of googling I haven't been able to find even a single alternative to ADC with similar pricing and selection on generic drugs. Well aside from the somewhat pricier ReliableRX sister site which offers many of the same drugs with a 30% markup. What's weird is that the Cipla drug I am searching for, which ADC doesn't seem to carry (perpetual OOS), is available at ReliableRX, but the price is sufficiently high that I don't think I would really be saving anything over my insurance copayment for the US name brand version.
ADC is the only online pharmacy I have found with both good selection and reasonable prices just like a real pharmacy you might find in India or other third world countries. Of course if I actually lived in India I could just walk down the street and find another pharmacy that had the drug I wanted for a similar price.
I don't work for ADC. I just haven't been able to find another online pharmacy with comparable prices for asthma/allergy medication, and having lived some years as an expat I know what typical local prices are for the drugs I am buying. That's how I know that most online pharmacies are price gouging in a big way. The only reason they can get away those ridiculous prices is because rich first worlders who might make more in one hour than the locals make in a month are willing to pay them. If a pharmacy tried to get those prices locally they would quickly go out of business. ADC is the only exception I have found. Their prices are more or less in line with what I would pay at local pharmacies as an expat. Why they chose to offer their drugs for fair prices even to rich foreigners I don't know. Maybe they have principles or something.
