This got brought up on the J.Crew Aficionada blog the other day, and someone posted the text of an email J.Crew sent them when they asked for more details. Here's what it said:
"Happy to answer your questions
and provide a little clarification. Canadian store and the Canadian
website prices will now be brought in line, so that you are being
charged the same. You will be charged in CAD from now on. The prices you
will see are the same prices that the items on the Canadian site were
before the transition to Borderfree, just will be shown in your currency
instead of USD.
Just like now, you will not be charged any
duties. That cost is absorbed by J.Crew, and it will not be charged on
your order. You will also never be charged any duties upon delivery.
For
your shipping, the good news is that the fee will actually be a little
less. Right now, we charge $9.95 USD which is 12.82 CAD according to the
current exchange rate. After we make the transition, the flat rate fee
for shipping will be 12.00 CAD when there isn't a free shipping
promotion offered.
Another bit of good news is that you will
still be able to use promotions. The promotions may differ from US
promotions from time to time, but some may be the same - you'll still be
welcome to apply any eligible promotions to your order during check
out. For example, we just had a promotion a few days ago for other
international customers that offered 40% off certain items along with
40% off sale styles when the US customers were getting a similar
discount."
