Shipping charges are always combined.
The most that we charge for shipping is $1.95... If you buy multiple items, please wait for an updated invoice that reflects the combined shipping before you pay. If you pay the automatically generated invoice before we can adjust the shipping charge, any shipping charge over the $1.95 will be refunded to you by the time the coins ship.
Sellers have the right to set their own prices independently, but some manufacturers place restrictions on how these prices will be displayed or communicated to others.
