The prices in the catalogue are shown here in GBP. However when you integrate them into your product list and store, they will be displayed in the native currency that you have set in your Shopify store. We will update the prices in your currency weekly based on the currency spot rate at the start of that week. All conversions will be rounded up to the nearest whole currency unit - i.e. nearest pound, dollar etc. to avoid odd looking prices.
When you make a sale we will charge you in you native currency for the costs of producing the print, handling fee and the artists share. By charging you in your native currency we will carry the risk of exchange rate movements within the week.
