Good logic but bad math. Assuming you shoot 6 Gb a day on the  
average, 90 days of photography would produce 540 Gb of image data.  
If you stored the data on DVD discs you would require 115 DVDs at a  
cost of $57.50. Of course you would exceed the capacity of your 500  
Gb hard drive so you would have to buy another. Incidentally Staples  
sells 100 packs of DVD discs for $29. Sometimes even cheaper on sales.

Incidentally, 6Gb of 10 Mb pictures is 600 pictures a day, every day.  
How do you find time for anything else?
