I sold my blue rays on ebay, I sold 21 blue rays for 140.00 did I get a good deal?

You got a good deal at $7 apiece. Used dvd's go for $3-5 in stores, less on ebay at times, even $1 or 2. And just for comparison, The Matrix is listed for $5, The Expendables is listed at $6.57. Two decent and popular movies sold for less. Transformers Revenge of the Fallen is listed for $7. I'd say you did just fine and good a good price.

Yes,

You didn't even get ten bucks a pop, I'd say you got the short end of the stick.

Or maybe not, depending how your view on internet downloading is.
