I get some garbage emails from time to time, often advertising stuff I neither want or need, and I just delete them unopened. Back a while ago I got some emails with political sounding titles. They got the same treatment, instant deletion.
Sometimes I get emails from companies I've done business with before, usually for PC related stuff and electronics, etc, and often I will read them to keep up to date with products and pricing, but anything unsolicited generally gets deleted unopened... especially if it's from a store named Harvey Norman. I'd never shop there because the whiney assed owner is a billionaire maggot who lobbied government for years to impose greater taxes on online purchases from overseas to make his stores 'so-say' more competitive. He eventually got his way, not that his sales improved any over online sales, and now Australians are paying even more tax than before on overseas goods.
As for junk mail in the real world mail box, that gets thrown in the bin unread as well.... when I get my way, that is. Shaunna sometimes likes to read through the junk mail, and I'll allow it to keep the peace [don't tell her I said that... ssshhh], but it gets binned as soon as she's done with it.
