If Cataract Clear is so good, why does it cost much less yet contains 2 or 4 times the amount of the main active ingredient & comes in big 10ml bottles?

Costcuttersrus suggest you compare Cataract Clear to other eye drop products that also use the proven active ingredient N.A.C. to treat cataracts if you have not already done so for your own reassurance and peace of mind. Costcuttersrus keep costs low by cutting out things like boxes or other packaging which all costs money. Costcuttersrus keep our overheads as low as possible in all areas while ensuring that the product itself is top quality as that is the most important thing in our humble opinion. 
By keeping costs low, our fabulous products are made more available to more people to buy for use on themselves or their beloved pets.
