Which one you prefer ? Postal service or e-mail service.

I would prefer E-Mail service over postal service because, it is faster.

I prefer to Both.

I prefer e-mail

this depends on what are we sending. If you are sending hard things then you have no choice but to send it by post. If we are talking about downloadable music or videos, then we can send them through downloads and emails. I do prefer online services as much as possible. But again, it depends on the nature of the product.

i would prefer email services

i like email services only. bcoz its cheap, easy and fast.
