It was an admitted error from Paypal and an oversight from Dave.
I suggest it was an oversight on your part. You had a chance to use the correct address when you paid; I know, I have used Paypal many times.
I recently purchased some items from Kershawguy - and I did not use his web site - you are very much incorrect to insinuate it is a "known issue" with Dave's web site.
I paid via paypal, and for some reason, paypal chose to use as my default address my local walmart!!!
I called Dave, but there was really nothing he could do - I would never expect someone else to pay for a mistake I made. My mistake? I did not carefully check that Paypal was using my correct address.
Note that I have lived in the same place for 20 years, and I have never had items shipped anywhere else besides my house.
I don't even know how Paypal chose to put my local walmart super center in my list of delivery addresses.
If I were going to be pissed as someone, it would be Paypal -
Fortunately for me, I called the local Walmart and spoke to the manager who told me that only managers can sign for a package that comes in USPS.
I went to the Walmart on the delivery day (USPS tracking) and picked up my package at the customer service desk.
I take exception to your trashing Dave for something that is obviously out of his control, only you and Paypal had the reins in this case.
