Competition, labor, shipping costs, and other factors require frequent changes to your store's product pricing. Working in a spreadsheet application, for certain tasks like updating pricing in bulk, is easier than in a web interface. However, the process of exporting data, then importing that data into a spreadsheet app and then importing back into Shopify can be a pain.
Painless Product Pricing is fully supported by the Appbox development team. It is quick and easy to chat or call Appbox support to get help.
