Would you trust this craigslist response?

I'm selling a college book on craigs and got this email, not so sure about it.....


Hi,

Am glad it's available. I'm going out of the state to Madrid for a
family emergency but I will instruct my assistant to prepare and mail
your payment which I'm sure you will get in about 4/7 business days.
I'll add $30 extra for the delay. I'll pay by cashier check so send me
your info (i.e full name, mailing address and your phone number) so
payment can be mailed out immediately. I will also make arrangement
for pick-up which will be after you must have received and cashed the
payment.

Awaiting Your Info Asap
