"Playing cat and mouse with someone?"
Who knows... Considering this was mentioned during a frat meeting perhaps they were planning an event at a range and were trying to buy a considerable amount of ammo? In that case he could've given the frat house address as the ship to address. (If he was paying through PayPal his dorm address could be listed in that account as it may be the billing address for the credit card so that may be where the seller got the address from?)
The thing that's also puzzling is why would the seller make a mistake on the date of shipment? I'm leaning towards thinking this transaction raised a few flags and was being watched by the FEDS. That would account for the missing shipment, and the address situation had Heinrichs purposely OR innocently not registered the dorm addy...
I googled "selling ammo on e-bay" and this was one of the top links.
I don't now if it helps, but I tried. The article is from 1999 and I'm gonna go back now and read the WHOLE thing, but from the article's begining, it read like e-bay was getting ready to quit selling ammo about that time.
When did this guy say he was trying to purchase his e-bay ammo?
Thanks.
