In addition to offering flat rate shipping, $9.99, we offer a 10% discount on multiple item orders with value of at least $30.00. That's a minimum saving of $3.00, plus you save the $9.99 shipping fee by ordering the items you need in one order. The minium amount you save is $12.99. Postscript; I note that the system isn't quite working. We will honour any discounts by way of refund if needs be, however, we are currently working on a work around.
