I just found out that TesterKorea is doing an amazing sale 11/26-11/29. I am positive I won’t be able to resist this one! 30% off all these brands :). I’ve ordered many times from this site and it’s just great. They do charge shipping but their prices are so low it makes up for it!
Beautynetkorea is also doing a sale with some great gifts and discounts. This doesn’t seem to be strictly a holiday sale but its going on now! Beautynetkorea is a great place to get products. They do have a bit of a limited selection.
Yesstyle is also having a sale which is giving 15% off and free shipping on all orders! Use code CyberMonday. Sale runs now through Dec 1st! Yesstyle has a huge selection of things and not just beauty products. I’ve found their prices to be a bit higher but they sometimes have stuff I can’t find elsewhere and Free Shipping!!
