block heater cord

While on vacation in Europe, I bought a new Calix cable off ebay.de for Euro 25 including free local shipping, or about CA$37. All I need to do is cut the Euro plug off and install a North American plug.

It certainly beats paying the crazy price they are charging for this cable over here.

Need MK6 (2011) Jetta TDI block heater cord

Does anyone know where to get the block heater cords in CANADA/USA? --- other than at the dealer? My Mom drove off with her car still plugged in and I'd like to get her a new cord for Christmas..
