I get the idea to not to start a "who bids most"-challenge, but like this you need to go higher then you potentially needed for that coach or you have to bid for a bigger amount of coaches (like 10) and at the end you have 5 coaches you cant afford to pay or you have 2 coaches with similar strenghts.
The game has just reset, and obviously most people are hurrying to get coaches (even though I don't really think they're that valuable). This means that a lot of people bid on a lot of coaches.
And those players like me that are more careful and try to bid a reasonable amount and only on very few coaches (because who wants to end up with 10 coaches) are having a hard time... No biggie though.
I assume things will quiet down on the coach market in a few days and it'll be much easier to pick up a coach with 8-10 stats for a decent wage ;)
EDIT : Just saw this man "Garry98" on the staff tab with an incredible wage. The type of problem that we're facing is that someone paying 30k a coach will probably leave the game, and the price will be impossible to reach for every normal player right now and in the near future.
Here are two very recent examples:
Somebody else won the Derek Renner offer by offering 20007, you off..
Somebody else won the Antonina Bradtke offer by offering 22000, you off..
