Dear Mr XXX,
During the wonderful pre-Christmas season topbonus is giving you yet another reason to celebrate: show us that you are an active member of the topbonus Program and an avid fan of earning miles!
In our Christmas Special we are giving 1,500 topbonus award miles to each of the first 500 topbonus members who register before 24th December 2012 via the link below!
With 1,500 award miles you already have half the total number you need for a topbonus Topdeal Ticket. So the sooner you register, the better!
