I have 4 boxes to sell, one has been opened but is in pristine condition - that one will contain 7 extra bonus sheets. Please specify if that is one you'd like to buy. Buy 2 boxes and receive a 5% discount ($47.50 each - $85 total) ; buy 3 and receive a 10% discount ($45 each - $135 total); buy all four and receive a 15% discount ($42.50 each - $170 total)! To take advantage of the discount make an offer for the correct amount and I will invoice you accordingly.
