The ETEKCITY backpacking stove is already a killer deal at its normal price of $14.99. Similar products like the MSR PocketRocket 2 or Snow Peak GigaPower cost more than three times as much and offer similar size, weight, and functions.
Currently, the ETEKCITY stove is available as a Lightning deal for $4 off, or $10.99.
The deal is good for the next four hours. But don't worry if you miss it. It goes on sale fairly often or you could always get a two-pack for $18.99 and give one to a backpacking buddy. And there's a virtually identical one from Sahara Sailor for $8.99.
