I tried to use the $15 off orders over $75 code posted previously but Paula's Choice said it was expired. I found this one listed on the CashRewards website. Paula's Choice currently have other promos running that make it a good time to buy!
Other promos running till 06/05/2015:
1. Free standard shipping on all orders
2. Three free samples on orders over $5
3. Free Resist 25% Vitamin C Spot Treatment on orders over $100
What I bought:
2% BHA Liquid $29.70 (normally $33)
Then I added a Resist BHA9 spot treatment trial size (which is half price at the moment) to get the order over $30 and the referral discount (thanks frutter) was automatically deducted. I also got three bonus free samples and free shipping, order totalled just under $20!! Very happy as I wanted to buy these two things anyway :)
If you are close and need to get an order over $30 the samples are usually $1-$1.50 and they last at least 3 uses (I have found anyway).
If you are a new customer (or delete your cookies so the website thinks you're new?) you can use my link for $15 off $30. Both referee and referrer receive $15. Link: http://goo.gl/LSr0o1
