I wonder if it is , in a subliminal manner, Amazon trying to convey you are getting value for money . Before you think I have been on the funny woodbines , even though I have never smoked, I worked in IT starting on mainframes and ICL as they were ,Fujitsu now , used to sell mainframe processors for millions of pounds . The processor itself was a cube about 18 inches cubed in size but they put them on cabinets that were substantially bigger to make sure the Customer didn't get irked at paying such a huge amount of money for something that didn't look like it was worth anything like that.
