International Customers Please Read:
We value our international customers and want to provide them with exceptional service and a quick delivery time. However, while we take every effort to ship items as soon as possible and to fill out very detailed customs forms, sometimes packages are delayed in customs for several weeks. Although this does not happen often, it has occurred in the past so we want you to be fully aware of the shipping delays that may take place. Please understand that once we ship an item, we cannot control the service transit time. Transit times may vary considerably and they exclude weekends and holidays. Moreover, transit times may fluctuate with package origin and destination, particularly during peak periods.


International Duty & Tax Charges:
International customers should be aware that many countries will charge a duty to import products from overseas into your home country. You will be responsible for the payment of these duties. We want you to be fully informed about your purchase from us. Please be sure to check with your country’s customs authorities regarding the duties that may be added to your purchase. Please check these rates BEFORE you hit the Add To Cart button so you are fully informed about your purchase.
