About Customs, Duties & Taxes
Recipients of international shipments may be subject to import taxes, fees, and customs duties (hereafter, "Import Fees"), levied by the customs office of your shipping destination. Import Fees vary according to the customs regulations of the destination country. Components that play a role in Import Fee calculations are (among others):
Product category and price
Shipping costs and package weight
Customs clearance channel
Import taxes based on custom duty amounts
Customs policies vary widely, and some countries don't charge Import Fees for shipments that fall below a minimum value. Contact the customs office of the destination country for more information.
The recipient is the importer of record and must comply with all applicable laws and regulations of the destination country. Customs delays can affect original delivery estimates.
- Customs offices in some countries or regions require the importer of record to provide a form of identification before releasing a shipment, such as a Passport, Tax ID, etc.
What payment types do you accept?

What’s a Security Code?
- Security codes, sometimes called card verification (CCV) data, are the digits (usually 3) on the back of your credit card. For cardholder security, we ask you to input these digits during checkout
Why can’t I check out?
- There are a few reasons why you may not be able to complete checkout. Here are some solutions:
- Credit Card Number or CCV: Double check that your credit card number has been properly entered, ensuring that no spaces are between any of the numbers.

Are there any hidden or surprise fees or charges?
- On purchases, you will pay for the cost of the items you order plus any applicable taxes, and that's it!
Why do I sometimes see different prices for the same item?
- Our insider's list emails and site homepage display the lowest listed price for a given product. Some products are available in different sizes, colors, styles, or other options that may be listed at higher prices.
