ditto here. and when i called back to accept my offer the random girl who answered the phone knew my name, and acted genuinely excited for me/pitt at my decision. on admit days at other schools i could barely get a smile out of the wet-fish admissions staff.
did you receive an initial acceptance letter or were you accepted from the waitlist? if original acceptance, when is the second seat deposit due.......... if from waitlist, how long did you have from verbal agreement til deposit was due?
WL. i took a few days to think it over before asking for an official letter. upon receipt of official letter, 2 weeks.
seems appropriate to me really. it's so close to when final deposit due anyway. also, fact is if you end up going there it's in YOUR interest for their yields to hold up. I imagine a lot of WL people are tempted to say "yeah" just to feel better and have options. they only want you to say yeah if, barring some major acceptance or life event, you will attend.
I always wait till last minute possible anyway. i figure either way it's worth fedexing. cost between overnite and three day is nominal, so i just wait a day or two before it's due and overnite the check.
