Dear sir,
Greetings.
Working with several world most renewed ecommerce site like eBay, amazon, Google Merchant, as well as other platform of Magento, OsCommerce, Joomla, WordPress, BigCommerce, helped me experiencing all the issues and the way to get them done.
So, i should say, just need the instructions and other things will handle independently here.
Also i need to know which platform you are using for the store.
Please feel free to ask if any query necessary.
Sincerely,
ahmsuza
