Many people have done the research about the care of a BP. Poorly guided people who live in remote regions can feel even more frustration. They did the research but something may be missed. It isn't worth placing blame.
I have lived in places where even a simple heat lamp and finding bulbs involves a 6 hour one way driving trip to purchase. Even the most expensive, fastest shipping may mean a 7 day delay.
Many of these places are in the north, high arctic for Canada. Such places often have a store, any type of store, that sells time delay plug-ins meant for plugging in the block heater of your vehicle. Those places may have car battery blankets in stock. These can be great to help keep temps in the safest ball python temps possible until something better finally shows up in the mail. A car battery warmer wrapped around the tank or placed under it may work great if the power goes out.
