Amazon should only be carrying first-quality. Same with just about any retailer. Nordstrom Rack might have some second-quality shoes, but not all of them are seconds.
There are a few places to get the shoes discounted. Forum user allaboutshoes offers first-quality AE shoes at a discount, but does not accept returns, so you must know your size. Since you already have McAllisters, you should be good for any calf offering on the 5-last.
