those prices seem pretty similar to what i've found out here. so, uh... how much is one supposed to tip would you say? obviously, it would vary depending on how good of a job they did - but... is it 20% like most other things? if it's $120, would $150 be about right? i'm always afraid of not tipping enough, so i generally overtip, just to be sure - the delivery guys around here make bank when they come to our apartment, i swear.
