I have noticed that some items on here (depending on what they are) can be reused, used once or only used a few times. For some items it says in the description if it is a once only thing or not & for others it doesn't. I think that in the description of ALL items it should say how many times you can use it. By doing this it would help a lot of people like me because personally i have bought quite a few expensive things thinking it was a good deal because i could use it again and then realizing my mistake after i have bought it.
