Many a times I have the tendency of purchasing electricity units(tokens) in bulk and staying for months without them depleting.Its convenient for me since I get my money cyclically.Therefore when I have money I buy many units.However,it comes with a disadvantage.Whenever am buying the tokens after depletion,I pay a large sum due to monthly standing charges.This has made me change my electricity consumption pattern.I have since considered buying my units monthly.I have since realized that I can save a lot by the monthly purchases.Whats your take?
