From your Product Locker, click the ‘X’ in the upper right-hand corner of the product you would like to delete
Some products will have a black box with the Sony logo as the icon - it is difficult to see the ‘X’ in these cases, hover your mouse in the upper right-hand corner of the icon and the mouse arrow will turn into the selection hand and you’re able to click to delete
You will receive a prompt verifying you wish to remove the item
Click > Yes and the product will be removed
Click > No and you will be taken back to your product locker
In my case, the product item that I wanted to delete was represented by a SONY LOGO which is all black with the white letters spelling out SONY. While these instructions are correct, I could not actually see the X in the upper right-hand corner. If you moved your cursor to that spot, the cursor changed from an ARROW to a HAND and you could click and delete as the response above indicates. Just you have to move the cursor around to find the correct spot.
