Query: a commercial rip-off

I felt ripped-off after reading the last page of the book from her series where the author is hawking her web-site GIFT STORE to purchase t-shirts and coffee mugs. YEP the true colors shining through are greed. All this author wants is to split up what could have been ONE awesome book into 5 different parts so she can make more money.Yes, the first book in the series was free on kindle....but that's where they hook you in. At the end of the first book, I felt there should be SOME resolution and that the story should tell more about the characters. WRONG....it feels like each book is just a reincarnation of the same theme.First book was free, second book FIVE bucks, third book SIX plus bucks, and the fourth book was TEN bucks...minus a penny. The last book in the series doesn't come out until 2011. I feel utterly ripped off. I feel like I wasted my time and I wish I'd never read the first book. I'll never pay for another book from this author again.
