The short answer is almost certainly that the record label has placed significant restrictions on the price. It's not just Beatles albums. Lots of albums are cheaper to buy used on Amazon than MP3s on Amazon. It's an imperfect marketplace. A few record labels control the supply of MP3s and Amazon places little control on used album sales. Also, MP3s are a better product for people who want MP3s. They have instant delivery, no need to rip the CD, and physical storage requirements. The advantages of a CD are resale value and collectability and better archival capability, but I don't think most people care to store FLACs.
