As low as $1, you get from Officework a Willow Blue Jug
I immediately look online for a best deal on Willow Alpine 5L Jug Blue when I got back from camping. Our friends really have this jug and it was superb useful during the event. Luckily, Officeworks offers it now for just $1! I thought it will cost me more since it really looks high quality and there was no drip tap even once during camping that I remembered. It can store 5 liters though it looks so small with sturdy drinking cap. It guarantees 10 years as it is insulated with dense polyurethane. I guess, it means keeping drinks cool even for a longer period of time. Well, take a look at this offer here, you might need one on your picnic or day trip too: http://www.officeworks.com.au/shop/officeworks/willow-alpine-jug-5l-blue-wi20371
