Classic Spin

Is there a difference between BLOKUS Classic & BLOKuS CLASSICS GAME?
I want to buy this game, but knowing little about it – I am confused by some of the listings on stores online. I know there are a few spin-off games, but I am interested in buying the original, main Blokus game.
Amazon has two versions of the original version, one for $30 plus shipping (retail $30) and another for $23.38, free shipping (retail $25). This is confusion as the boxes, title, and retail price is different between the two. Are they the same? Are the different? If so, how?

They are the same. If you notice, one was made by Educational Insights (the original publisher), and the other is published by Mattel (they bought the game rights from them) So thats it.
