We prefer to ship out immediately after payment has been received. The cost of shipping varies per item and we try to give a reasonable estimate. Some of our more delicate items may be heavier due to the packing, therefore increasing the shipping cost. If you are an international buyer , please check with us ,before closing on the purchase. The choice to add/not add insurance is not optional on the "one of a kind,fragile "items. These cannot be replaced. There are no refunds on any of our items.
