I saw a skirt on Sale written R149,25 written on a yellow sticker printed Extra 25% when you buy 2 or more items on sale. When I got to the till,carrying the skirt ,a nail polish on sale,a lip stick on sale. The skirt was R199 ,I enquired and I was told by a guy who was serving me that when you buy 2 or more clothing items on sale you get it 149,25. My question is: Where is it written only clothing items on the yellow sticker ? No where he says too
