Selling a dryer on craigslist... below email



I got a very similar email, I don't understand how they benefit from sending you a check? But I will not proceed obviously, just curious.

I'm glad it's still for sale. I'm going on a vacation to London but I
will instruct my assistant to prepare and mail you your payment which
I'm sure you will get it in about 5 - 7 business days. I'll add $30
extra for the delay. Check/Money Order is the means I can pay you
with. If this is acceptable by you, Send me your info i.e full name,
mailing address and your phone number so payment can be mail out
immediately.I will also make arrangement for pick-up which will be
after you must have received and cashed the Check/Money Order..
Awaiting your info
