I have had a module written for specific levels of discount for OS Commerce, allowing discount from 5% to be given to all customers ordering over the internet. However, the company receives many phone calls on a daily basis ordering by phone which, does not qualify for the discount.
Therefore I would like a method added to the module that disables the discount when ordering by phone. This has to be done by admins and not customers as those who order by phone will not have internet access. Or, it could be done by creating specific accounts that do not qualify for the discount so that a person in the office taking the order uses this account and no discount.
Please be certain, this is not a full modification it is just a mod of a mod so not a very big job.
