Buyer Beware with Amazon Caveat Emptor
With me you can speak and discuss the items you want to buy. I am passionate about these puzzles and the likes of Amazon are not. Amazon sell lots of things and as a buyer you cannot discuss what you are purchasing.
If you know what you want and do not care about support or after sales you can go to the likes of Amazon. I tried to sell on Amazon and it was a nightmare it was impossible to describe items the way I wanted as Amazon had previous incorrect listings that over rode my description. I also bought on Amazon . However the buyer cannot 'examine' or 'inquire' about the purchase with Amazon . In their wisdom of errors Amazon will often send the buyer something misrepresented or not described correctly.
Finally I will beat any Amazon price if I can!
