I've been looking for a cheap hands-free drink system while riding and saw this at my local BigW. Even at $39 (Original price) it's a good deal, but when scanning it comes up at $10. According to Website, this deal is only available in store and not for Delivery. A quick search of my local stores all show low stock.
Employee edit: Don't rely on the website stock indicator to represent actual stock in store. Please call up before coming in to check and please don't give staff a hard time when there is no stock in store but it says it is online as stock information does not get updated regularly (separate company manages bigw online) :)
