Amazingly, not everyone who develops for woocommerce forgot what WordPress is about.
These two guys made a awesome job integrating PagSeguro (its like Paypal for Brazil ;D) with woocommerce FREELY!
Not being like some developers who charge about 90 bucks for a integration plugin like this should got them 5 stars already, but what made me rate it 5 stars wasn't it. The easy integration and management the 'idiot-proof' configuration screen and the awesome developer's website made me rate 5 stars.
And, if you are wondering... It works. ;)
Thank you VERY much dudes.
