I have finally used the coupon code MC51 from Mastercard to get free international shipping from Gilt, a private shopping club (flash sale site, sample sale site, private sale site). The best thing about my purchase is that I ordered a pretty heavy KitchenAid mixer. The coupon allowed me to ship it to Russia for FREE saving $175.
The mixer does require me to use a power converter. But this is not a big deal considering the fact that it costs $1000 USD in Russia and it costed me only $281.79 when purchased on Gilt. The only problem is that Food Grinder attachments are no longer in stock on Gilt. So hurry up until the mixers are in stock.
