"Schwag" (or swag) is a term that has several meanings. "Schwag" can refer to low-grade marijuana or to any promotional materials given out to employees and loyal customers as a part of promotional campaign. Likewise, you can purchase all kinds of "schwag" from a company if you wish to support what it's doing and to be a spreading the good news about its products everywhere you go. I'm currently working on researching and ordering some schwag for OnlinEnglish promotion. Incidentally, I thought I'd ask you a few questions dealing with this.
What kind of schwag do you usually receive? What items you think you would buy? Please, take a minute to answer these two questions! Thank you :)
