I generally ship daily except on weekends, holidays or when I am on buying trips or vacation trips. If payment is received by 10 a.m. central time, it will generally be shipped same day. If not, I will ship next day. BECAUSE OF THE LARGE INTERNATIONAL POSTAGE PRICE INCREASE, PLEASE CONTACT ME ABOUT INTERNATIONAL SHIPPING. Always happy to combine shipping whenever possible, most of the time it will be the same cost as one item. Thanks and good luck!!
