Sales Tax and VAT (Customers in the EU)

MyCommerce™ is required to collect sales tax for the (US) states where they have locations.

There was a change in the VAT laws effective 7-1-03 that requires MyCommerce™ to collect VAT from customers in the EU. VAT is an additional tax, similar to Sales Tax. The rate is variable and depends on the country in which the customer lives.

Possible additional costs

If you pay by debit/credit card NO extra fee will be charged by MyCommerce®. If you pay by check, postal money order or similar payment option, MyCommerce® might add to the price of the eBook a service fee. You will always see any possible additional costs (VAT, sales tax or service charges - only if applicable) within the order process before you definitely order the eBook.
