Based on your request for a large package of concentrated instant juice powder, I would recommend either the Phytoganix Tropical Fruit Powder, which is available in a 300g size for R1400, or one of the Footy's Cooldrink Powders, which come in sizes of either 450g for R174.95 or 170g for R75.95. The Phytoganix option would provide you with the most juice powder by weight/volume for the cost, since it's close to half a kilogram of tropical fruit flavoured powder. I hope one of these larger bulk size options is helpful for your needs. Please let me know if you would like me to check other online retailers for an even larger package size.
