Broadway Flea Market

I said this in the other thread about Flea Market, but my general rule of thumb when buying something - do I need this and will this still be here/cheaper as the day goes on? Toward the end of the day, prices begin dropping and things become very cheap, so somethings may end up dropping in price by then to be more affordable. In terms of what to know - Wicked's table is always pretty pricey as is Hamilton, but there's plenty of other tables around and it really is a find a good deal type situation. It's definitely one of my favorite days and I always look for it it (except for the year it was in Roseland and everyone was overheated and miserable).
