My niece had a nice visit with us. And left her laptop behind rushing to the airport last night on her way back to Prague.

Anyone with experience what couriers offer good mix of price and service level shipping something this size to Europe? Thinks to do/not do to avoid customs hassle?
So far quick online quotes for delivery sometime next week range from $160 (Canada Post Priority worldwide) to over $340 (Purolator). Maybe others who have been in same/similar boat have tricks'n'tips....

[Realize this is not AC-specific; happy to move it elsewhere, but it's not Canada as a destination, and in general Travel forums will get swamped by US participants....so hoping our friendly AC/AP community can help!]
