Ooh I know this!
MUCH WORSE... I was trying on a pear yellow diamond pendant yesterday and it was $17,300 in Canada and $15,200 USD... and our dollar is STRONGER right now! HOWEVER... skip on over to my yellow diamond thread because the Canadian stores are being quite reasonable (at least Bloor St. was!) with the exchange rates being as they are right now... she said "we don't do price adjustments or sales ever... but we are sensitive to the strength of the dollar right now" and recognized basically that it makes absolutely no sense for a diamond to be 20 or 30% more expensive here when the dollar is at par. So when I said I'd love to buy it today (if you're serious they're listening!) but would have to ship it back to NYC (I had NY send in a few to look at in person - a good idea!) and buy it there and pick it up in person (would actually have been cheaper to fly there and back and get it than get it here for $17,300 + taxes), she spoke to her manager and they came back with the US skew price ($15,200) AT yesterday's exchange rate... which brought it to $14,909 CND!!! It actually came to LESS and I didn't have to pay duty or smuggle it over and stress the whole way. I could not BELIEVE it - I kept waiting for her to say, "but we have to charge this..." and she didn't!
Make sure when you bring it up that they know you're ready to buy and that you're also ready to buy that one or the equivalent in the US. And go to Bloor if you can - Yorkdale is less lenient with a LOT of things for some reason. I really wanted to buy here - I'd rather support our economy than the US's (no offence to our American neighbours!) ... plus it was just cleaner... but was not going to spend $3K more to do it. That's almost a LOVE bracelet! LOL. Would rather spend $3K on a vacay centred around picking it up down there than blow it for no reason! I was really really impressed that they did this and am sure if you deal with Bloor St. they will be reasonable with you as well, especially on a bigger ticket item like diamond rings! Good luck!
