I realize you're on the receiving end, but for general knowledge, be careful if shipping airbags. These must be packed in specially designed boxes and have specific labeling on them, like batteries or chemicals. I know the fine for not doing it is substantial.
They're not expensive, you can buy "kits" from shippers with the proper box and packing materials included for a reasonable price, used to be around $25-$30 depending on size, but I'm sure they've gone up since I last bought one.
