Tara does spam with emails a bit, sometimes I would get 2 in a day. But, she has replied to any queries I have sent, always within the same day, and offers a 100% money back guarantee. Also, she has sent me free items (after the initial free reading), not every email has been asking for money. I have seen some of the results she has told me about, but I am yet to see some of the bigger predictions she has made come about.
Many people have said she shouldn't charge at all, but it does depend on the service. If she performs something which requires materials then I think she has a right to charge for those. However, it seems like this is what she does for a living, and just like everyone else she has bills to pay etc. and needs money to live on.
Since I have spoken to her through email, not just by entering details on the website, she has actually sent many fewer emails asking for money for a ritual (less than 1 a week), but she does send me freebie readings and such.
I feel that the service she gives can be overpriced, however if you believe in the power of positive thinking to bring about positivity, then it feels great to have someone in your corner helping you out when you feel down so that you don't start to bring about negativity.
