National Home Gardening Club Took my money with promises they apparently don't honor. Internet

Paid this company $24 for 2 year membership. I was a little surprised to receive the bill for $24 since their original letter stated $12 for one year and said nothing about needing to pay for 2 years up front.  However, I sent it because friend said she had good luck with them but had dropped her membership anyway.

They made promises of free gifts and grocery coupons and gave a web site to request these things.  The web site doesn't exist.  It takes you into their site to subscribe to their magazine. When I tried to contact them thru their provided customer service email address it was undeliverable. I would like my money back but apparently this is just another scam so don't expect to get any return.
