The CBS O&O's have ramped up the "Like us on Facebook" rhetoric.
If you like them on Facebook you could win Audi A3. The rules state only one entry per person, but it appears you can like each station (14 in all) and that would give you 14 chances to win the car.
But, the rules also state that you must live in one of the markets of these TV stations. So if you live in a market with a CBS O&O, go to all the O&O station's Facebook pages and like them. It will give you more entries and a chance to win. So head to the FB pages of WCBS-TV, KCBS-TV, WBBM-TV, KYW-TV, KTVT-TV, KPIX-TV, WBZ-TV, WWJ-TV, WCCO-TV, WFOR-TV, KCNC-TV, KOVR-TV, KDKA-TV, WJZ-TV and like them so you can win.
Why the O&O's care if you like them on Facebook? We have no idea.
