So, my school has some service to where they will hold all of your letters of rec and send them out whenever you need them sent. Sending them out though is not free, and the faster you want them sent out, the more you pay. Anyhow, I applied to my school's med school and they requested my letters of rec. The sad thing is that not only did I have to pay to have my letters sent across the street, but the office wrote down the wrong zip code (its the same as for the office) and the letters got there a week later than they were supposed to. My school is lame.
