I tried to do my homework before ordering from a business like Tadd Wholesale. Any auction company that is on eBay will have unknown damaged goods.
So far, the items purchased have had an accurate description of any damage or missing parts. Unless the box is opened to inspect the item, there is no way I can think of to know if the item is damaged or parts missing. If I purchase an item with the description of "New item in damaged box" for instance, I run the risk of finding a damaged item upon opening. I also shop auction houses that do not deal with eBay.
Even so, I have to read all the descriptions, policies, and return policies. If not, then I will get "burned" at some point.
Reason of review: Happy for another reason.
