I'm in Mass and temps have been too cold to get online orders of crix or PW's for almost a month now, so I feel your pain.
I too have resorted to spending upwards of 6-10 cents a piece and getting 200 crix at a time, every 4-5 days or so from the local pet stores.
It looks like there might be one day next week that the temps could get warm enough overnight to squeeze in a shipment, but it's going to be a gamble at best.
I believe the heat packs most places use when shipping are rated for 48+ hours, but doubtful they last that long. Plus, it looks like 20 degrees is the lowest they will go for overnight temps and still deliver. My guess is anything lower than that and no amount of heat packs are going to be sufficient.
I guess I don't have any advice other than to say you're not alone and hopefully someone has some ideas that can help. I hope the temps get warmer soon, at least warm enough for places to start shipping crix to us!!
...and I'm sure we'll see at least one response that says "start a dubia colony", which is great except for the fact that it'll be spring before the colony gets going...LOL :mrgreen:
