This is the product of ICI. Production cost is high as compare to the price. Also the demand in the market is very low. Only persons having problem in thyroid use it. Due to that reason, really really short. Most stores sell, if available, on their own price. CLINIX in lahore sells on retail price, AND it may available at it because they are bulk buyer.
P.S. my mother also use it. It seems really difficult when new bottle needed.
Anyhow, good luck to all you have got it with the help of others.
