Query: Over priced Kindle products

Hi,I received my Kindle as a Christmas gift and immediately thought it was the greatest device since the invention of the wheel. I purchased about ten books from December 2009 to March 2010. Now the party is over. They have raised the prices so high it less costly to go to Sam's and get the hard covered copy. A least I can pass it on to my friends. I will not purchase anymore products (books) until the cost becomes reasonable. I urge others not buy a Kindle or the books until the cost goes back to being affordable.Thank you.JAN
