I was in the market for some board games and did my usual check of Amazon.com/uk and found the shipping costs quite prohibitive. I stumbled on this site where they have 20% off in stock items which brought the price down a bit but then noticed that if you have an auto club (RAC/RACV etc..) membership it stacks with an extra 10% for an overall 28% discount. (ie it takes the 20% off first, the 10% off the smaller amount - got me for a sec)
Combined with free shipping for over $125, it worked out to be a good deal for Games of Thrones and Mansions of Madness and close enough to US prices without freight AND GST is being paid (some tax is staying in the Country! :) The 20% excludes trading cards, MTG (Magic the Gathering I assume) pre orders or items already reduced. Not sure what the exclusions are on the auto club discount but it worked for these items and I hope it works for someone else.
Only problem is no NSW Auto clubs that I could see, only other states.
