How to Make a Mint Condition Lego Box

Brady Bunch: I have been of a mint condition conundrum at the moment. For my birthday, which was back in June, I really wanted the Saturn V Lego rocket that was released around that time with 1,969 pieces. It was one of the most impressive Lego things I'd ever seen. So I'm seriously wondering if it's still on sale, whether I should buy a second one so I can make one and keep one in mint condition in a box as like a display thing.
