Have purchased about a half dozen Eagles in the past few months from the "best" Macy's here in Cincinnati.
While they're not considered the "high-end" of what Macy's locally has to offer.....like most local Department Store competitors like Dillards and Parisian, that "honor" is held for RLBL, HSM, and the occasional Abboud.....they'd be among the better shirts on their shelves, and at least a couple cuts above their house brands.
Typical white and blue pointed-collar broadcloths/pinpoints with barrel cuffs carry an MSRP of about $60, and sell in the middle $30's during the very common Macy's promotion. I think the OCBD's are comparable. I've purchased several.....usually with french cuffs.....on clearance for anywhere from $18-$28. Marshall's pulled out of Cincinnati some time ago, but I've not checked availability at TJM (probably because I literally can't stand walking in those particular stores).
Without going into my closet and looking, my recollection is that all were made in China.
I've also bought a few Eagle Shirtmakers shirts before and I found that the sleeves were not the size I was use to. In other shirts I wear a 34/35 but this size in the eagle shirt was too short. I ended up giving the shirts to a friend who they fit perfect. There is a guy on ebay that sells the eagle shirts. I did find them to be a decent quality shirt for the price though.
