For the past few years, in addition to magazines and newspapers discontinuing print subscriptions (especially free ones), many companies also stopped sending out paper coupons and such.
For example, Rogers stopped sending VIP customers coupons with the bill and instead sends a link to a web page where you can print one yourself. I recall hearing about the airline Delta requiring passengers to print their own plane tickets when they book online instead of issuing them one themselves.
Of course they explains this as being green and environmentally-friendly, but the truth is that they just don’t want to spend the money on paper and especially ink, which as anyone with a printer knows is expensive.
