Sorry to put a damper on things.
If you guys are buying and shipping these canisters from overseas, be warned...shipping aerosol cans (cleaning, hair spray, paint etc) are prohibited by international couriers ie. DHL, FedEx, USPS, TNT etc. for personal users like us. You have 80% chance the items won't make it out of the US.
Having said that, I did order a can of paint from the US and was delivered to me a few months back. I took that risk since it's like the price of a large coffee.
