Important note about SHIPPING:
·
ON
Multiple item orders only,
NOT on single item orders
,
SHIPPING COST totals can become UNREASONABLY HIGH due to the necessity for Ebay to add up all of the individual shipping costs for an estimated “not to exceed” total ship cost.
A high ship cost total on your order will be corrected by us, but only if you place your multiple order and WAIT to PAY,  UNTIL after we send you an invoice with COMBINED shipping.
Don’t use a cart
to order your multiples because it forces you to pay immediately on checkout, and, we can’t then invoice you for combined shipping on your order once you have paid.
