Got an email from Priceline:
There's no better time to stock up on your favourite Haircare brands with 40% off Haircare* in store and online. Hurry, it's only for Tuesday 12th and Wednesday 13th May 2015!
*Excludes Ego, Regaine, Hair Accessories, Baby and Hair Electrical. Savings based on Priceline's normal national selling price. Savings and stock may vary in stores and online. Limited exclusions may apply in some stores. Please check with store staff before purchase. While stocks last.
Additional note: 7.7% cash rewards (http://www.cashrewards.com.au/priceline) (Thanks Andrew for the tip)
RRP = Regular Rip-off Prices.
Though, 40% off the RRP is not too bad. Got some stuff that I couldn't find in the regular supermarkets.
