I still get over 100 paper letters a year from Spectrum (previously Time Warner) about various deals even when I already had their service. I've had Google Fiber for awhile now, but they keep coming. I've been storing them all in a box to eventually mail them all back to their HQ. It's quite a hefty box a this point.
