If you called them and asked them to assign it, they will not give you the incentive listed on the job board unless you specifically ask for it. They're not being sneaky, necessarily, it's just the schedulers can't see those online incentives, or at least that's what they say. To get the online incentives, you have to self-assign on the website. If you are new, you will have to complete a certain number of shops before getting self-assign privileges. In the meantime, you can verbally ask for the incentive amount on future shops. It will be difficult to get them to agree to give you the incentive now, but you can still try.
