Add the hair styler you want to your cart in August and note its total with the best active code, so in September you can tell whether the Glow Fest price is a real cut.
Coupon codes at protouchskin.com top out at 25%. Savey tracking shows the highest code ever recorded here is 25%, and 25% is also the most common code. The Glow Fest in September and the Pay Day Sale both advertise up to 50% off, so a sale is the only time the store advertises more than 25% off. This matters most on the costly hair devices, such as the Airshot multi-styler and the Air Sleek straightener, where every extra percent is worth more rupees.
Up to 50% is the most a sale offers, not what every product gets. During a sale, price your item two ways: the sale price alone, and the normal price with the best active code. Take whichever total is lower. Glow Fest also adds extra cart discounts on top of the sale price, so check the final total in your cart, not just the price on the product tile.
Codes here expire within a few days, and new ones are most often added on Saturdays. Check the coupon list on a Saturday and use a code within a day or two of finding it.
