It's not hard to find distributors/wholesalers. But you can't buy medication from distributor without licence number. I have tried.I'm going to find the distributor for these and buy in bulk. Like 6 months supply.
You can befriend a drug store owner and ask him to provide you good discount. Never go to drug store which is the only store in its area. Go to the part of your city where there are like 10-20 medicals next to each other. You will get discount here only. 30%-40% discount is easily achievable. Go to Marwari drug store who doesn't use computers for billing.
Secondly, find alternatives to your 30/tablet. Go to > https://www.medplusmart.com/ and search for the main compound of your tablet (not the brand name). And there you'll see alternatives to your 30/tab starting even from 3/tab.
There are so many more things you can do. Let me know if you need any help.
