calumc, if you found a seller for that price, please share the link. I've been looking and so far no luck for smaller quantities in that price range.
So what I have found at this point is the DIY kits for the clear 1 inch domed case badges. Roughly without any printing on them they will cost about $1.50 a piece. Then you figure the cost of printing and large amount of labor to cut it all up and put all together and postage, I'm thinking either $4.50 to $4 depending on if I feel that the amount of work was alot. Of course, I would also like to donate some of that money to Linux Mint. The nice thing about going this route is that I can customize the logo o be either on any color background, so light or dark version will be available.
The 2nd option, which I'm waiting to get pricing information on. Is 1 inch square vinyl stickers. These come in rolls of 500! And would be limited to 2 or 3 colors. Full color versions for that low of quantity is very expensive (we're talking a couple of hundred dollars). So that will not be an option at least at this point. So I don't have a price yet, so I will get back to everybody when I find out more. One thing about having these stickers is that they are more versatile, since they are nice and flat and can take a beating.
So if people are still interested, please post here. But understand this is not an official product and more of a side thing for me to do.
