Some people were saying firsts relative to seconds weren't worth the risk.I think he's just saying that Daltons are discounted enough to be worth it (they're not discontinued in chili).
Let's look at the Rush St for example:
$197 clearance first
That's not such a great deal. Here's an example where the shoe bank rocks, black captoes:
Park Ave first: $385
5th ave first: $385
Park Ave first: $327 (RDA)
5th ave first: $279 (RDA)
Park Ave 2nd: $229
5th Ave 2nd: $219
That's pretty good but we can do better.
Rutledge 2nd: $177
BB 5th ave 2nd: $169
I'd go rutledge 2nds over a first quality park avenue at that price even at the RDA price. Obviously not a perfect example but I think it illustrates the general idea.
