there web site is a scam, no back button, no edit, no conformation before you are charged. it says if you buy the original and add the 7.95 extra for shipping plus another 7.95 you can recieve another set. and firther down the line you can change colors but when you change colors it adds another set. totally misleading. i was charged $72.20 and it took some determination to cancell that order the easiest way is to go to cs at 800 566 2888
