This is a pretty random thing but I wanted to mention it because these items rarely go on sale.
You can get Peter Thomas skincare for up to 80% off right now. These are higher end skincare products and they almost never go on sale. I use some of these items and I usually have to hunt down a discounted voucher to a beauty supply store to get them for decent prices.
Also, if you spend more than $10 you also get a free 1oz sample of moisturizer included automatically in your cart.
