Swapping for points widens swapping possibilities. On those occasions when one person has an item the other really wants but the other has no interests in the swapz offered, points can make the difference between a swap being done or not.
In fact, swaapping for points no longer means that swapz involve just two people doing a deal. With the introduction of points a swap deal can now become a swap circle involving several users who can all get what they want!
Ideally, to get points, you should swap an item you have with a user who has points and then swap these newly aquired points for what you want. As the swap circle grows and more swapz take place and satisfied swappers will list more items leading to more even completed swapz.
With the addition of swapping for points the possibilities are limitless.
