It's interesting to look at PayPals approach to currency choice: https://www.paypal.com/cgi-bin/webscr?cmd=p/sell/mc/mc_receive-outside And here's their approach to inter-currency conversions: https://www.paypal.com/cgi-bin/webscr?cmd=p/sell/mc/mc_convert-outside Some comments on their conversion approach... RE: The most readily available information on currency exchange rates is based on "interbank exchange rates". Interbank exchange rates are established in the course of currency trading among a global network of over 1,000 banks, and are not available through consumer or retail channels. Consumers may use these rates as a reference, but should not expect to use interbank rates in transactions that involve currency conversion." JRP: Okay, so they refer customers generally to a concept, but not to anything specific. FWIW, "Paul Volcker once noted that trade is more affected by 10 minutes of movements in exchange rates than by 10 years of trade negotiations." http://www.ft.com/intl/cms/s/0/327383a2-666b-11e3-aa10-00144feabdc0.html#axzz2qIxzyWLm RE: To obtain actual retail rates, contact your local financial institution or currency exchange, or check the rate displayed in your PayPal transaction. JRP: The best they offer is a vague "ask your bank" or after-the-fact "check the receipt". Yet forex "noise" often has a greater range than the profit margins vendors count on. By ensuring that vendors can choose their preferred price stabilization index in the web payments environment, they're in a better position to manage risk. -- Joseph Potvin Operations Manager | Gestionnaire des opérations The Opman Company | La compagnie Opman http://www.projectmanagementhotel.com/projects/opman-portfolio jpotvin@opman.ca Mobile: 819-593-5983 LinkedIn (Google short URL): http://goo.gl/Ssp56
