I may be all wet with this theory but here is my take on why some either never receive their W&E mag or receive it a week later than others.
Last month when I received my W&E, I noticed it was rather thick, well, it was two copies stuck together! Both were in the plastic sheath cover, but they were litterly stuck together. The second copy did had a mailing address label on it so I put it back in my box for the next day pickup.
I would be willing to bet what happened to me is not an isolated case, since the sticking together of the plastic sure seems feaseable to many others being delivered.
I am not sure if it was the glue from the label or another source that caused it but W&E might think better of possibly changing some procedures on packaging.
I very easily could have kept that extra copy and I am sure many would have, but you just cannot do that to a fellow detectorist when it has a label on it. Now if there had been no label, then it is a different story.
