Allen Edmonds takes either 19.22% off or $90 off select styles during its 90th Anniversary Sale. (Discount is reflected on product page.) That's tied with our mention two weeks ago as the best discount we've seen from Allen Edmonds since Black Friday, when when it offered 50% off slippers. Sales tax is added where applicable. Offer expires April 30.
A best bet are the Allen Edmonds Men's McAllister Wingtip Oxford Shoes in three colors (Walnut Calf pictured) for $245 with free shipping. That's $90 off and the lowest total price we could find. These are available in widths AAA to EEE and sizes 6 to 16, although not in all size/color combinations.
