Product doesn't work that well. Okay, I watched the infomercial about the ROBO-STIR. Novel idea, I thought I ordered the first one and was supposed to receive the second one free. Then I was given the option of ordering another set and get one free for only $9.99. I received them 2 months later and was billed $80.06 WHAT???? I was charged $19.99 twice and $9.99 twice and received a total of 4 robo stirs. What happened to the buy one get one free???? I called to ask them about and they said I upgraded and I have to pay because it is not really for free I have to pay tax and S/H is free but they charged me $13.98 S/H. Again WHAT???? So I asked her again to explain why I was charged for all 4 robo stirs, and she said I upgraded and I ordered 2 sets. So I was charged $19.99 for the 2 sets that I ordered. .....okay Then why did I get charged $9.99 for 2 more sets?? She said that I ordered another set and that is the price for those So I asked "How many sets was I charged for total?" She replied "2". ....Okay then why was I charged for 4 and I was only shipped 2 sets. She said the free ones will arrive soon?????? In the end she offered to let me keep the ones I have and she would credit my account only $15. or shipp the extra set back at my cost for credit of $9.99 I know the definition of FREE and charging me for four sets when ordered 2 is not buy one get one Free.
