Through Dec. 31 Indigo.ca is offering 20% off when paying with MasterPass, and this works on electronics, including Kobo ereaders like the Aura ONE [indigo.ca]
. I linked my Discover Card to my MasterPass account because that's the only card I have that doesn't assess foreign transaction fees. There are others, of course.
I think Indigo's shipping fees vary nominally depending on destination in the U.S. For me they charged 16.60 CAD. Also, e-bates offers 1% cashback on Indigo.ca electronics purchases.
The Aura ONE was 199.99 CAD + 16.60 CAD = 216.59 CAD. Or about 160 USD. See attachments for documentation.
