ohh btw
If you went into a shop that sells the Pads, you would see the condition of these pads before payment was taken. Perhaps this is the way to buy them in future.
If you are getting seconds from Sony themselves, then thats just plain bad Salesmanship.
I would imagine that there must be some legal piece of paper stating that they are second hand and not a brand new product. Has to be some legal requirements to protect the buyer.
Wish I knew a bit more about law, just my take on it.
