Just a heads up - I think Marks and Spencers has discontinued their free delivery to Australia for any size order. Looks like you have to spend a minimum of £30 to qualify. Fair enough, always thought it seemed too good to be true! Just a shame when shopping in the sales as they don't seem to reserve items so by the time you have filled your basket most of the stuff has already been bought. That's where putting in a couple of smaller orders is helpful.
This was in an email I just received;
Free delivery to Australia, New Zealand, Canada and the US applies online at marksandspencer.com only, with a minimum spend of £30. Offer applies from 14 October 2013 for a limited time. M&S reserve the right to discontinue this offer at any time. Offer excludes orders placed on M&S Outlet online, 1-click orders, furniture, rugs, electrical items & lighting.

All products are sold on a Delivery Duty unpaid basis, so please be aware that recipients outside the EU may have to pay import duty or other taxes.

The following products are excluded from international delivery: Food, Wine, Flowers, Gift Cards, Hampers, Furniture, Electrical, Lighting, Made to Measure shirts, Personalised Cards and selected Beauty Products. See individual product details for more information.
Seems fair enough, the cost of delivery would have to be fairly significant and could wipe out all the profit if people are just buying one or two items for a couple of pounds. Better for them to implement this minimum spend now than to disscontinue it altogether :)
