Cheaper by the dozen

I ordered a screen to cover my patio door so I can keep the bugs from coming in when I step out onto my new deck (maybe when it cools off). The box arrived
today and seemed really heavy for what I ordered. I was right.
They sent me 12 instead of just the one. At first I thought I must
have hit "enter" too many times, but no, the packing list had only
one and they only charged me for one. When I called customer
service to let them know that they had made a HUGE mistake,
they were more than happy to send FedEx back tomorrow
to pick up about $1000.00 worth of merchandise.
