magazine ads

Open any magazine and you are sure to find a ton of advertisement for everything from gorgeous hair extensions to getting the perfect tan to weight loss programs such as quick trim burn and cleanse reviews. It all makes me curious as to how many people actually go through the back of the mags for these advertisements? Have you ever bought or used anything that was marketed, advertised or promoted by celebrities on these pages? I haven't found anything that I really must try so far, but one never knows, does one!
