I have two firm steps that a coworker wants to buy from me. they are pretty much like new but I dont know how much to charge her for them. she told me to let her know. what would you charge for the box that inclines and the other step that has two pieces(blue and purple sections) along with 3 dvds or videos? I paid 60.00 for each system. I am never good about pricing items i want to get rid of,any help would be appreciated,thanks!
