OOP: who got the reward for the DEs?

When Harry and Cho wander around Hogsmeade, they find many posters 
of the recently escaped Death Eaters:

"The poster ("By Order of the Ministry of Magic") offered a thousand-
Galleon reward to any witch or wizard with information relating to 
the recapture of any of the convicts pictured." (p. 558, American)

At the end, many DEs are rounded up, included a number who escaped 
Azkaban. So, who, if anyone, got the money? Will this matter in Book 
6? What if Harry gets a lot of Galleons and starts becoming enamored 
with his newly earned wealth (on top of the sizable amount he 
already has)?

Could one major theme in book 6 be money? It sure seems as if the 
Weasley twins will become successful entrepreneurs. A set of foils 
for Harry's monetary temptations, perhaps?
