Archibald, I know that they're not the best, but there's no need to continue to provide no help at all, when I'm getting my stuff free, and didn't read ask for comment on what he commented on. I'll definitely worry more about quality when I'm buying at a price, but quality doesn't matter when it's free, in my mind.
I think quality should always matter but I'm going to go against the grain here and say that a free suit is always good quality for the price. The emphasis my fellow forum members are trying to show should be that you need to look for the highest quality you can, which can be hard to discern at MW. Like others have said you'll be getting a fused suit with plastic buttons at that price, there's almost no chance of anything else. So really you need to look for the best full wool suit you can find and then make sure that the shoulders fit with your natural shoulder line as opposed to hang over the edge.
If you can do both of those, and get one in a staple color like grey or navy you'll be doing just fine. It will be more than a suit for a "pinch," It can certainly be your go to suit throughout college. More than half of what makes a suit look good or not good is fit and halfway decent cloth. To the average eye you'll be dressed to kill in a fused MW suit if it fits right.
Don't take the harsh tone around here personally, some people tend to forget that not everything can be Loro Piana. If you need to buy at retail prices in the future don't return to MW, but if you get it for free then rock the hell out of it.
And FYI, there is truth to the fact that you can find a better suit at Goodwill for $10... but it takes time, patience and that's $10 more expensive than the one you're getting! Go forth and question no more.
