Rocket fuel camp stove. I have one. It’s awesome.
This is the fuel you need for it: Jetboil Jetpower Fuel for Jetboil Camping and Backpacking Stoves, 100 Grams https://www.amazon.com/dp/B079QH62KW/ref=cm_sw_r_cp_api_glt_fabc_JFK1TKTR00A442ZWVVDP?_encoding=UTF8&psc=1
Wow, you are right. I thought there would be no way Amazon/JetBoil would ship fuel canisters - I was wrong.

The problem is that it's $20 for 1 canister. Typically it's $5 at the store. A $15 premium for the extra shipping hassle. A last resort I'd say, if Walmart or other local shops don't work out.
There are other random brands on Amazon, but I don't trust those for my fuel canisters. MSR, JetBoil, Optimus, Primus and a few others are my short list. GasOne and Perune are not on my radar.
