Mass Inventory Upload

If you want to list a lot of items and it is too time-consuming to list them via the Sell Item screen, you can Mass Upload your items into BrickLink via an XML file. How you generate that file is up to you.

The following is a sample file containing 3 items to be listed. The first 2 are basic and the 3rd is advanced. Detailed explanation of all tags follows. You may cut + paste the below lines of code and test the upload verification process to see how they come out. Each item in your file goes through thorough verification before being accepted for upload. If there is an error on an item, the verification process will show you the error(s) and ask you to correct your file and re-submit it.
