Bloomingdales is having their Friends & Family sale, where you can take 25% off with the checkout code FRIENDS. Included are a bunch of Barbour coats, with waxed cotton jacket models starting at $169 and quilted models starting at $149 (note, orders over $150 ship for free). Since Barbour no longer allows European retailers to ship abroad, this is about the lowest price you’ll get in the United States.
I personally wear the Bedale, which is a shorter version of the Beaufort. Take a size down for a slim fit and factor in $75 to have the sleeves lengthened. The sleeves on the Bedale are notoriously short, but you can get them adjusted by sending your jacket directly to Barbour or dropping it off at a local Orvis.
