Marshalls New Terrible Return Policy

Hey everyone,
I just wanted to give a heads up about a new policy being enforced whimsically by various Marshalls store managements. I buy all the time at Marshalls (like TJ Maxx or Ross) and when I went last week, I picked up (among other things) a pair of $100 mens shoes for my brother. There is a large sign by the front of the store (as in all Marshalls) explaining the return policy. 30 Days with receipt for money back. After 30 Days, you get store credit. If you lose the receipt so they give you the lowest ticketed price for that item. Which all in all is pretty fair. I got home and gave the shoes to my brother whom they did not fit properly. Long story short, I went back to the very same Marshalls store within the 30 day time frame and they refused to take the return claiming that they do not accept returns on "high dollar items" (ie, anything over $50). I spoke to the manager there at length saying nowhere does the sign indicate there is any limitations and I clearly would not have bought these shoes had I known! No-go. He refused the return and told me I can call the corporate store. Marshalls Corporate told me that the individual stores have the right to add and or edit the rules of the return policy EVEN THOUGH there is no specific mention on the posted sign in the store, and that basically it is my tough luck. Im out the $100 for the shoes, but i figured I would try to warn people and/or see if anyone else out there ran into a similar problem. Up until this point I have been a huge marshalls fan, probably spending upwards of $3K a year there, (yeah, I buy alot of cloths!), but this is a dealbreaker if I ever saw one.
