Came across this while removing some items from my eBay watching list. They have recently discounted up to 15% off RRP for a well-reviewed and received mattress. Kicking myself for buying it at retail price during Black Friday sales. With the 5% eBay Sitewide discounts, it reduces prices even further. Not sure if it is the lowest ever, but certainly one of the better prices yet.
Full breakdown of cost for all mattress sizes, after 5% off code PERCENT5:
Single - $130
King Single - $165.54
Double - $205.91
Queen - $233.37
King - $269.71
As always, enjoy :)
Note: Shipping varies depending on location. Free shipping for Sydney Metro and Melbourne Metro. Other locations range from $9.80 - $69.
