Put your empty cosmetic containers to good use by taking them to the Tangs Customer Service counter at either Tangs Orchard or Vivocity between this Thursday to Sunday and receive a $5 Beauty Voucher in return. Each person can redeem a maximum of 3 vouchers and one voucher can only be used to offset purchase of one item (i.e. you cannot combine the vouchers to be used on one product). Other terms and condition apply so please check in-store for more details. The vouchers are only while stocks last and based on past year's experience, they may not necessarily last the whole 4-day period. My guess is that the vouchers cannot be used on Estee Lauder group brands.
