I bought my wife 3 packs to try from an REI garage sale the other day so here are the 2 she didn't want and I'm just asking the price I paid, and then a Jetboil Helios that has been used for 2 nights out and is still practically new, other than the auto igniter not working.
All prices include shipping:
Osprey Atmost 65 size small (blue) - $130 obo
Gregory Z35 size small (blue) - $85 obo
Jetboil Helios - $105 obo
