Any points that remain on your account as a result of a bonus from purchases, out of stock items, difference for items exchanged, etc. are yours to use in any way possible on the the High Street Market site.

They are not redeemable for cash, non-transferable, and non-refundable once they are on your account. If you would like to wipe out and claim the balance of points on your account, simply make a purchase using any leftover points on your account to zero it out.
