I was taught as a child to open plain envelopes first. Checks, credit cards, and other important stuff are put in boring envelopes.

I worked for a CC company and when we mailed checks to customers we told them “This check will come in a plain white envelope.” And the amount of people who thank me for letting them know because they might have thrown it away.

I went to a small concert and you could buy their music on a flash drive. That was awesome. I like that option

At a anime convention there was a table with various CDs of the band playing that night. I couldn’t go to concert, but bought a CD to support them even though it was going to be a slight inconvenience to rip it. I still have all my old CDs (I don’t really have that much so haven’t gotten rid of them. I keep them in a plastic container) so just put it with the rest.
