The Thermacells are worth their weight in gold.A friend at work was telling me that Walgreensand places that sell heated curling irons sell the gas cartridges. He told me they(Walgreens) also sell the cards. According to him they are allot cheaper then buying the Thermacell refills..I would imagine any place that sells hair products carry the cartridges.Of course they're no good without the cards.It might be worth checking into.
