Has anyone used White Linen in Ixonia (outside of Oconomowoc) for their chair cover rental or ever heard anything good or bad about them? They are very reasonably priced ($1.75 for the cover and sash or $3.99 for delivery and set up). I am considering putting my own covers on to save money and as they are the cheapest I found I am wondering if it is too good to be true. Any input??
