Hi,

It works for me not completely. It works when it is free shipping, but ones it isn't free shipping, but local pickup is enabled, the flat rate isn't displayed...so only the local pickup is displayed. It looks like the script thinks local pickup is free, so that that's the shipping a customer should choose. But a flat rate is also possible of course.

Realy handy thanks for your contribution !
