Not sure if this is available in all Woolworths but picked up one of this Festiva FT2240SP Double Burner Butane Gas Stove with HotPlate and Windeshield for only $22.50 at Woolworths Livingston (WA). RRP was $90. Not sure if I'll ever use it but it was definitely a bargain and handy to have ;) Happy hunting!
Appears to be showing up at select stores nationwide (e.g. Livinston, WA, St Clair NSW, Kings way, WA, Campbelltown, NSW, Warringah Mall, NSW )
