Would you sign up for a contest online?

No, I sign up for nothing on-line.

I'll send in 3x5 card by mail everyday though.

No you will suffer spam and spam and spam.
I mistakenly signed up for something that wanted my insurance renewal dates (surreptitiously) and now my e-mail is almost unusable.

I do publisher's clearinghouse online. And also other contests through reputable websites.

Only if it's a product I use.

I can. Its less risky for men i guess. 😐

I have a reversable vest,so if I ever need to it's-shoop,swerve- and then they go looking for another criminal,the plaid one.

Depends on the company and the product.

No. This is the way scammers get your information. Then they blast you with advertisements or whatever.

I have done it online, but only with companies I know and use.

99% of them are scams. And even the 1% that offer real prizes will sell your info a hundred times over before anyone wins anything.

Yes
