Few reasons:
1: they were the only place with Deluxe Luke in stock; and with the exchange rate ship/tax are next to nothing.
2: It's done via Paypal; if something happened and it ghosted you can always just dispute the transaction.
3: Just a HT; nothing I urgently need so waiting is NBD.
4: No Other Options
Added a crucial one you forgot.
I’d rather pay retail plus $22 in shipping for him and get him a month from now than pay eBay rates and get him sooner. This is not a $400-$500 figure.
All I'm saying is I know someone who's trying to track down an express mail package sent more than 5 weeks ago (to Canada) and they haven't found it yet. I guess that's on PC if it goes missing though, not the buyer.
