I would say it is retailers doing that, not AIB partners. Newegg sold the black pack for 599.99 USD at launch, but for $656.00 USD (converted from CAD) in Canada. Same AIB. Ships from same warehouse.
Newegg even tried to screw me out of the games. I noticed them taken out of my cart just as I was clicking to finalize order.
After purchase I sat thinking for 20 minutes on canceling and going with 1080 Tis.
