There is a sign hanging from the ceiling with the Hi$-$Fly name and logo$.$ Anyone who makes ten baskets in a row from a line marked on the floor gets a free Hi$-$Fly basketball. In addition, anyone who participates by attempting at least one shot, whether they make any baskets or not, is entered in a drawing to win the Hi$-$Fly backboard$/$hoop$.$ Now you are wondering what other sales promotions Hi$-$Fly might be using in this store.

There is a bin of keychains near the Hi$-$Fly backboard$/$hoop$,$ with a sign that says $$Have a ball on us$.$ They are free to anyone who wants to take one.
