Yeah i always pickup a few here and there to max the order if not much catching my eye or kooks depends which cheapest at the time. have been getting a few generic kangeroos as i'm filling a tube of them. for me sometimes the cheaper it is the better it is for me and my strategy
i did order a roll of 2016 koalas last year but got sent 2016 kooks instead...I not complaining about that a touch really as 2016 kook a great design..
