Swarovski seem to have extended their 3,000 miles promotion (for purchases from CHF99) until the end of December. It says for 'sparkling jewellery' in the link, but I presume that it applies to other items as well (such as chains). They are also offering 30,000 miles to a lucky winner:

Not sure if this should be posted in the competitions thread, or in the thread dedicated to Swarovski itself.
