SASA has been one of my go-to online store for all things beauty. I purchased a lot of thing from SASA such as skincare, makeup, and bath&body products. If you love Asian products such as Korean or Japanese makeup / skincare then this is the place to go because they have soooo many brands and products to offer. Their prices are very competitive too, a facial sheet masks can go for a $1 each!
I also love shopping at SASA because I can get name brands with (sometimes) cheaper prices. For example: I can get Clinique or Estee Lauder or Lancome products there, sometimes they go on Sale or I can buy the sample or travel sizes so it's cheaper than buying a full size.
SASA also have special promo offers such as Free Worldwide Shipping for a certain amount of purchase every few weeks or so. That's when I usually shopped ;p
