I am setting up a new grass root program at my son school. I need advice as to what is the most efficient way to put up the badminton court in the gym. The info i need is from where to get the floor anchor/socket and its cover. I found that some places offer them for like US$ 300 per pair is just too ridiculous !!! There is a website in Canada offering similar stuff for like almost 50% cheaper but the thing is they will not sell to me. What about the posting where can i get those too ???
