The thing is Mr. B, the address I put into the box is the same address I am registered as with PayPal. So they were the same. For some reason, my shipping address was completely different than my PayPal address used for billing and everything else.
So to be honest, if the person / company had paid close attention to everything, this wouldn’t have happened and it would have been brought to their attention through close study.
Nonetheless, I called PayPal to fix it since the site itself would not let me change it for some stupid reason - even the PayPal rep was astonished.
