10$ Contributor giveaways should be 9.99$

As topic says...if we have successfully contributed 9.99$ in a giveaway...and now if some giveaway is of 10$ then we can't enter that just because of difference of one cent...It might seem little bit greedy but in other way I have a kind of feeling which I can't explain... So it is my humble request to contributor giveaway organizers to consider such things. I am not any kinda forcing...it is just a request!
Instead of 10$ -> 9.99$
20$ -> 19.98$ or something like dat...
