Where do you guys get your packaging from? My mother has an eBay shop and deals in dried flora - she uses boxes that are specially designed for her creations, which cost a fair bit. I'm perhaps looking to sell some of my old games and such, and wonder what you guys who also have had a clearout use to package. My mother's stuff costs £2.41 to post also - I know that this may indeed change as I have seen people offering postage for like a pound. So yeah, what do you guys use to package your videogames/books etc. and how much did it cost you in postage?
P.S I have bubble wrap and such, so just like the jiffy bag or the box is all I want to know! I also have a student card which is valid for 10% off at Staples, however they are very expensive.
Btw, not self-promoting as I am not advertising, just using my mother's business as an example to show why I'm confused :)
