I have some single walled boxes with loads of bubble wrap and some 150 guage fish bags, i add a small drop of stress coat to the water before posting and they have been fine even in last years cold weather, do you really think i need heat packs? where i live at the moment temp is around 8 degrees celcius its just times are hard and heat packs are expensive and i dont really wanna bump up postage.
Any help would be great
