In App Purchase returning invalid products but all code seems correct

Question

I have gone through many posts regarding this issue that seems helpful. The code I am using is the same as others used for getting the product information. The only difference I can see is that people are saying their products are "Pending Developer Approval" were as mine are "Waiting For Review".

I submitted my app and then rejected the binary which seems in line with this guide:

My question is: do I have to wait for Apple to review my in app purchase before I can start testing with it?
