Do you plan to set up a WordPress-based e-commerce site, or sell products globally? If so, then you may want to consider providing your web visitors with the convenience of currency conversion on your website.
Currency converting tools allow your prospects to have the price of a foreign currency transaction converted into their local currency when checking out products online. It also lets your customers see the exact amount their card or PayPal account will be charged, displayed in their own home currency.
One advantage of providing currency conversion is that it lets visitors see and understand pricing in foreign countries in their own local currency, and makes it easier for purchasers to calculate their costs and expenses.
Fortunately, if you are a WordPress user, you can add currency conversion via a plugin to your website or blog, allowing your customers to quickly perform currency conversions to determine the cost of your products.
