Documentation for what? The fact that I and my Wife are disabled, or What Wally world is pulling? If our disabled status, well, unless you are either Social Security, or Medicare, Not to be rude, but it falls into nun-ya. If you are Social Security, or Medicare, you already have reams of Documentation.

If Wally world, It is well known. It went to the point of them having to go before Congress so the Documentation is easily available.
This was just a very few years ago. Sad thing was then, that the Gov. didn't announce the outcome of the hearings until a couple of weeks AFTER the Christmas Shopping Season. So Wally skated by once again. And in typical fashion, the buying public had already forgotten the scandal by the Next Christmas Buying Season.
Just as a quick example, I purchased a HP Computer a few years back. Before the purchase, I gave HP a call and simply ask, why is the same model # available at Staples and Wally so different in price? Different warranty or other?
I was told flat out, if purchased at Staples, or other Office supplies, if defective, it would be shipped by the store purchased from, and repaired or replaced. If from Wally, it would simply be discarded by the store, and a new one shipped. the explanation was that the Wally version would have the same ssn# with two additional numbers in it, and was totally a product of China, produced for HP. The computers sold at the Office Supply Stores Were built at HP in the USA.
This is not a Political statement. Just reality.
I run into this often in the Cutlery Industry, where one line of products of a given company is manufactured in China, and another like line is manufactured in the U.S..
The difference is, it isn't being hidden and passed off as an American product.
The thing that got Wally in real trouble was the Made In America Slogan. Many here will remember it well. It was proudly displayed on every rack of clothing. It was an attempt by Wally to quell the complaints swelling that Wally was stiffening American Companies to make higher profits.
They got away with it until Congress learned that much of the highly touted Made in America Clothing, was in fact, made in China,. India, Indonesia, You name it, and American made labels sewn in, supplied by Wally, saying made in America. That is what got them the HUGE Fines.
Want Documentation? Look it up! I'm not their attorney, nor have any interest, other than being aware of the scandal, and the outcome. It's just another part of History in the annals of time.
