Sunrise mart? The one near St Marks that's above the bookstore? I think they sell at $2.50-$3.00 a box. There's also the underground JAS mart that's below the bakery on St Marks as well. They're a little more expensive, but their ramen and other stuff is remarkably cheap (I buy hair wax from there, and they sell fino shampoo... that stuff is like crack for your hair).

._. maybe they'll replace her by the time i get to take elementary japanese I. or, i could walk into class, bow low, and go "初めまして, 恩師 Hanawa-sensei! どうぞ宜しく"
