Apparently you are automatically signed up for a "trial membership" if you make a purchase.
I have made at least six calls asking for an email confirming my cancellation and every time I am assured that I'll get the email within 48 hours. Of course it never happens. Tha cancellation confirmation number I was given on the phone doesn't allow me to access my account to confirm that it is cancelled.
The people on the phone never know why "you haven't been sent a confirming email" but "I'll take care of it right now"

DO NOT BUY ANYTHING FROM THESE SCAM ARTISTS!

They promise a 40.00 rebate. Not true, beware people!

I was charged $149.99 on 1/16/08 on my Master Card for a membership promising valuable coupons for groceries, Gasoline, car rentals, roadside services and other benefits. I received their material in the mail yesterday, 1/29/08. I logged into their web site today 1/30/08 and a message came that this is a scam.

Thank you for the opportunity to report this scam.

I received a phone call at home offering a free 25 dollar gift certificate for Walmart plus a gas card worth $40... I agreed to the free trial offer at $1.95. Having just received the materials promised from ValuePlus I was instructed to go online at valueplusonline.com/open/form/gc to redeem my $25 gift card. There turned out to be no such site. The materials I received included a coupon for $1000. free grocery coupons which I was instructed to mail to the following address: Value Plus Grocery Savings, PO Box 5034, Hopkins, MN 55343-1034. I hope that address proves helpful to anyone tracking down this bogus operation.

I was called sometime after 3pm on a Sunday by a woman that refused to answer my questions. She said I had to be transferred to a 3rd party "authorization center". I stayed on the line, because she told me she has my credit card; she provided the last 4 digits. She knew my name and my address. She said it was a courtesy call, but she also said I would be "charged a dollar". She said that the dollar charge was an "introduction" to coupons, and that I would also receive a complimentary $40.00 coupon for free gas. Again, she refused to answer any questions probing for details.

When I got to the "authorization center", they refused, flat out, to answer my questions. The only answer I did get was that this was for Value Plus Online. (http://www.valueplusonline.com/ ) When I tried to ask questions, they refused to answer. Instead, they tried to get personal information out of me. When I probed for why they were doing this, I was called an "idiot" for not wanting $40.00 of free gas, and an "imbecile" for asking the questions I asked. The "supervisor" that was helping me literally yelled at me when I told him I do not want their gas, or their coupons, or the $1.00 charge. He slammed the phone down. The number they called from does not take inbound calls. The website does not provide contact information. Since it is not possible for me to determine with 100% accuracy whether they are a scam or a legitimate company, I will not make any assertions or accusations. However, my experience was unpleasant in the extreme, and disconcerting. I found myself calling my credit card company to order a new card. (The "supervisor" said I had already "agreed" to charges...even though I did nothing of the sort.)
