[Plugin: Dippsy] Dippys Product Price Problems

I’m having some trouble with getting the prices of the items to display correctly. In Dippsy all of the products are set to $0.99. However, when I click the buy it now button the price displays in paypal as $0.90. I then checked all of the wp_postmeta dippsy_file_prices and they all are set also to $0.99. At the moment I’ve just hardcoded the price to $0.99 in the dippsy_shortcode.php, but Ideally I would like the prices to be controlled by the product settings and not hardcoded. Any help would be greatly appreciated. Thanks in advance.
