I think it was just the red ones the last time these were at this price but this time it's the blue and grey ones too. They were labelled at $19 instore although they only went back up to $12 online when that special price expired.

Thanks to ben1980 whose post inspired me to check what else might be on sale.
Great price!! I have had a Cygnett power bank for 2+ years now and it's still going, very impressed! Would definitely reccomend, especially at this price. I got mine for $80, for a 20,000 mAh one, and though that was a while ago, it's still working :)
