Great plugin, with sensible upgrade model!

The Flexible Shipping plugin works well and makes the most important features available in the free version. What I really liked is that the same company, WP Desk, offers an import/export module for quickly importing shipping rates from various carriers. The bulk import feature was essential for my store while the pro version was not, so it’s very cool that you are allowed to pick and choose. Both are great plugins that are very easy to use.
