That's some expensive pinkies, with 1CAD = 0.61GBP. We have on shop locally that sells at 45p/pinky, which I thought was a bit steep, but bearable. We have another shop locally that sells 10 for 2.50GBP. We could get them cheaper online, but its marginal when you factor in postage and far more convenient to collect them locally.
I cant imagine being able to raise mg own snake food as Char used to keep them as pets and wont even watch the pinky feeds.
