Hammacher Schlemmer has it's Sticker Printer (which is really a Prinics PicKit S1) on clearance at $29.95 (plus S&H). It is both hardware and software compatible with the Kodak Photo Printer Mini which was on FP a few days ago, but with a much lower price tag even with shipping. I am convinced (see below) that both printers are from the same OEM.
I just tested my PicKit S1 with the Kodak Photo Printer Mini iOS app, and the Kodak App recognized and interoperated with the printer well, able to output exactly the same high quality photo stickers. It seems that both vendor apps are all based on the same OEM software with just logo changes. The cartridges are also seemingly the same.
