Today only, Banana Republic cuts 25% off sitewide, even sale items, via coupon code "BRBOUNCE". That's tied with our mention from five days ago as the best sitewide discount we've seen from Banana Republic in recent weeks. (We saw 35% off sitewide for just a few hours three weeks ago, since expired.) Shipping adds $7, but orders of $50 or more qualify for free shipping. Sales tax is added where applicable and some exclusions may apply.
A best bet is the Banana Republic Men's Thomas Dress Oxford Shoes in Brown (pictured) or Black for $79.99 before the above coupon, $59.99 after. With free shipping, that's $80 off and the lowest total price we could find. They're available in sizes 7 to 13, although not in all size/color combinations.
