Do you recharge mobile online regularly or go for offline recharge?

Do you recharge mobile online regularly or go for normal recharge? Online recharge is getting in the trend now and it is not wrong to say that we do get good offers when we recharge mobile online at some websites. So what do you prefer when it comes to online or normal recharge? I prefer both of them; but mostly for me it is online recharge; at least I get a chance to get good discount offers and saves my time.. Regards; Raja Rana
