Hello everyone.
I need to disable all shipping modules .. reason , this company will calculate the shipping off line due to the fact that online shipping calculations for those items are way too high.
If i remove all shipping modules from the system . then customer can not buy anything from the store.
I also need to inform customer at one point during check out , that shipping will be calculated offline ( best way , cheapest way ) and will be added to the amount .


I was wondering if anyone knows on how to do this ?

Thanks.
