So here's what happens. When I right click on your link and choose new tab it opens on Amazon ca and the price is 106.15 CDN.
When I right click and choose copy clean link open new tab paste and go I get 79.99 plus 51.14 shipping and import to Canada for a total of 131.13 USD x about 35% exchange is 149.00 CDN. Not great.
So now that there has been interest in these products, when I sign into look at this order, the new re-order price has gone up by 15.00.
The algo has picked this up and is grinding a few more points out of the buyers.
