If anyone buys 3 DVD's, will he get a coupon for a 20% discount when buying the fourth DVD?
It's like a reward for the members who continue to support the distro, right.
I have a few a few ideas for the shop.
What do you think Jerry about calendars?
Lets say a Linux Lite calendar for 2016 that you can put on your wall.
Or maybe a LL calendar pack with 3 calendars: a wall calendar, calendar for the table and a small pocket calendar.
It's also a form of advertising, and usefull at the same time.
Next, Linux Lite pencils, lighters, key straps, keychains. People carry them everywhere.

Cups are a good idea. Coffee, tea and linux lite. The only thing is they are fragile so the packaging would have to be appropriate.
Magnets that you put on a fridge. Like a LL stcker or something just for the fridge.
