Can you "stack" discounts for pre-purchases

Hi, I have just seen I can get a premium, wifi package for 30% off.  With my 30% Captain's Club Elite discount, I thought that was a good deal.  When I rang to make the purchase, I was told I can't have both discounts. Have I been advised correctly, as on our last sailing we were given the special rate that was advertised online, ALONG with our Captains Club discount.  Do they now cap the discount you can get for certain packages?

That is correct, you cannot stack them

They used to stack them but you can no longer do so
