"Did not do work, but pricing was competitive with everyone else. Invoice got lost in junk e-mail, so did not think I ever received invoice, but I found it a month or so after job was completed again. If\when I have another job will call All Foam and make sure Invoice doesn't get lost in junk e-mail!
