Secondary Domain URL Redirection

I have a Primary Home Page Domain that I maintain a lot of pages on.  I have recently acquired and parked a secondary  domain:

My web host wants $30 a year to redirect the secondary domain url to my primary.

I was thinking I could transfer my secondary domain to a "Free Hosting" service maybe and then simply do a redirect on the home default page to avoid the eatra $30 bucks.

Anyone have any sugeestions? Thanks
