I want to spend 5000 Amazon Coins

[coopec43]

When I first opened an Amazon account I stupidly bought 5000 Amazon Coins ($50). Apparently I can only spend them on software for games and applications.(I think that is right)

I was thinking I would spend them on navigation apps such as nautical charts, scanners etc. (Of course I would not want to buy anything I can download for nothing)

Can anyone suggest a shopping list? I want to blow the $50 as I don't want to gift the $50 to Mr Bezos.

NOTE
My yacht is nearing completion in Western Australia. My dream is sail it overseas to ...?

Anything here?
