when you select your custom package... d2h shows your package along with a package that it suggests on its own. there is a submit button. it is not clear which one is actually submitted as you cannot select one of the two. and nothing really happens on submitting. i got no email. no sms. not sure what's happening at the moment.
Republic is preselected in the default 100 bundle. God knows if they are paying for this privilege. You can of course remove it.
26 DD channels of course are mandatory. Rest can be removed to save on the network fees. I selected a bunch of news channels along with Colors (priced at Rs. 19) and my total bill came to under Rs. 200 as the screenshot above.
