While I don't think it's fair to compare Macy's to Sears, I spend more money per year in Sears than I'd ever spend in Macy's. Certainly not on the clothing at Sears, but it's never been clothing that has made me shop there (though I have bought some articles of clothing there). Now, I have never been to the store in NY (do love the parade and someone brought that up in another thread today), so it may be an exception, but I just am not crazy about Macy on any level. I don't like "their" brand of clothing either and I hate that they carry less other brands because of it.
Before it was Macy's it had been Kaufmann's Dept. Store. My favorite store btw. They carried all types of brand names (and popular brand names too). Since Macy's come in, we just go to other stores to try and find the brands Kaufmann's use to carry and I've literally have had to turn to the net for some brand names. I really like Boscov's MUCH better than Macy's and while they don't carry all the brands that Kaufmann's used to, you can get some really good brands there that even Kaufmann's never carried.
JC Penney is the better of the two stores, IMO (macy's/penney's). If you wanna talk Neiman Marcus, well, I think they're truly the winner, but, opinions are like you know what.
