Reply To: Free shipping always activated

Yes, wait. Now I have a bigger problem. After disabling and re-enabling your plugin, the following url stop adding the coupon:
http://www.edinventa.com/checkout/?add-to-cart=491&quantity=1&apply_coupon=descuentosm

I have been been able to make it work with two coupon codes yet. Is it possible?
http://www.edinventa.com/checkout/?add-to-cart=491&quantity=1&apply_coupon=descuentoweb&apply_coupon=enviogratis

I think I have not modified anything else but the free shipping options. What could be going on? :/
