Hi all,
I've seen a couple of similar posts, but nothing solved, or quite right. I've spent all night on it, but my lack of expertise is preventing me from achieving it.

I have set up a group called free delivery (ID 5). The discount rate is 0%.

I have Free Shipping Options set up, to give free delivery when spend is >= £250.

Regardless of spend, I want to give customers in the applicable group free delivery.

I really don't want to use coupons.

I'm confident it's a fairly simple tweak to ../includes/modules/shipping/freeoptions.php but would really appreciate some help.

Thanks in advance

Martin
