I am a big fan of Physicians Formula cosmetics but find it expensive. I was hanging out for a Priceline sale but found that iherb.com sells the range for almost 50% the RRP in Australia on what seems like a regular basis.
A few examples of the prices (iherb uses US dollars, so I have converted using 7/3/14 xe.com rates for a better comparison)
Happy Booster Glow & Mood Boosting Powder
$14.67 iHerb http://www.iherb.com/Physician-s-Formula-Inc-Happy-Booster-G…
$29.95 Priceline http://www.priceline.com.au/cosmetics/face/powder/happy-boos…
Bronze Booster, Glow-Boosting Sun Stones in Light to Medium
$15.71 iHerb http://www.iherb.com/Physician-s-Formula-Inc-Bronze-Booster-…
$29.95 Priceline http://www.priceline.com.au/cosmetics/cheeks/bronzer/bronze-…
Postage is usually $4 via Global Priority Mail (but could be a little more depending on how much you order).
If you are ordering for the first time you can get $10 off your first (order over $40) by using my referral code OQA864 (or you get $5 for orders under $40).
Real techniques brushes are also much much cheaper on iherb.com, less than half the price that they cost in priceline. Great brushes if you are after them :)
