@akiratoriyama I bought through payzapp > smartbuy > pharmeasy > 49-buy > let it fail > (quickly) buy medicine > add 49 (there) > buy togather > pay. That's it. (Bit tricky, but u can do it).
I lost hours of time and Rs. 300-400 to self learn this trick. (Even their customer care executive didn't able to help on this).
