I got a scam call offering a free weekend edition of the San Francisco chronicle - should I be worried?

I just received this call and foolishly gave my name and address – I thought it was real. Then they asked for my credit card number, which of course I didn’t give. The guy then said he’d send an invoice. At that point I said I didn’t want to receive anything, I’d been misled, etc. but they hung up! Does anyone know what this is about and if I should be worried or do anything else? And yes, I know it was silly of me… but I like Sunday papers…
