+      $output .= '<p>' . t('This module adding amazon products to your site, with custom theming, caching, automated fetching, storing & renewal of product data.') . '</p>';
+      return $output;

In English, each sentence ends with a period. I would also avoid using & instead of and.

Fixed #4 feedback in MR

+      $output .= '<p>' . t('This module provide customization to Amazon Product widgets') . '</p>';
+      $output .= '<p>' . t('This module adding amazon products to your site, with custom theming, caching, automated fetching, storing & renewal of product data.') . '</p>';

The period has been added just to a sentence.

This module provide customization to Amazon Product widgets does not seem correct, as least because it should use for Amazon Product widgets and This module provide customizations.

This module adding amazon products is not correct, since there is no verb after the subject. (The Present Participle is a verbal form used as noun, not as verb.) amazon is not spelled correctly.

& is still used instead of and.
