Scope deals to good to be true?

[Heyupduck]

I am looking at the Bass pro web site, and even if you add 20% for the currency conversion the Leupolds VX1's there are still 65% of the price of cabellas

They say they ship to Canada... Is there something going on?

I am so close to buying, but am just wondering want the catch is

3x9 x 50mm cabellas $529cnd
Bass pro $279 (US?) which is $340 cnd

4x12 40mm
$279 - $340cnd

cabellas $589 - WTF????
