As part of the Earth Day, Tangs is giving away $5 voucher for each full size empty cosmetic/skincare/perfume bottle that you bring in for recycling. There is no limit on the number of vouchers per customer but the vouchers cannot be combined, i.e. you can only use one voucher per purchase. In addition, Tangs Beauty Hall has lined up a great range of S$80 exclusive beauty buys from brands like Guerlain, Kiehls, Bvlgari, Lancaster, Shu Uemura, Biotherm and Perricone MD!
