SNUFFLING reporter Andy Gilbert found a special offer at Watsons in Taikoo Shing. Buy a Dristan nasal spray and get one dollar off a packet of Dristan cold tablets. He bought both, but staff refused to give him his dollar. The coupon in the product was supposed to be sent, by the retailer, to an office in El Paso, Texas, which would then send the retailer a coupon worth one dollar. Moral of this story: If any overseas factor causes a price rise, the Hong Kong customer will have to pay it. If any overseas factor causes a price cut, we have to do without it.
