Sales against form e1

Sir, 

What is the proceedure you are following while transacting E1 or Sale in transist? Sale is a contract between purchaser and seller for a consideration. In order to avoid discloser of purchase value, pay tax @ 2% against C form and sell the goods against C form for 2%. E1 sale means transfer of title of the goods without unloading the consignment under transport and can save 2% CST again or otherwise it is an interstate sale.

Thanks
