Richard,
The cruise prices are as low as $2000 for a week - less than $300 per day - all inclusive. All depends on the ship/itinerary/dates. There are some pretty good bargains. None of the cruises I've chosen for example are full price. All are early bookings (Thanks to Ngaire), SSS, OnBoard Discounted and Brown and Keene discounted. You can find a cruise that will work within financial constraints if you are willing to be on a repositioning, Carribbean or FP, Offseason etc. cruise.
