Various members here over the years have done them so Im sure you'll be able to do it still. Although IIRC the majority have been decals and not stickers.
You could do your own using printer compatable clear sticker sheets. they have worked for me in the past and you can get them for Bubble jet and laser printers, although the BJ ones need to be sealed in something like Future to make em safe to handle with out rubbing off (sweatty mitts cause the ink to lift) Laser ones are solid so ne need to do the same.
