There are some common Financial, (a.k.a. Cashier) terms that may be relevant to bonuses. Conveniently, Bovada puts a Financial Q&A on its own page

The big one here is the general withdrawal limits. It is important to know that a player often cannot withdraw his entire balance after completing a bonus if the balance exceeds the amount per individual withdrawal allowed. This is something that you will want to understand and be fine with, especially if you are making a large deposit.

For example, the maximum check by courier withdrawal is $3,000 and may be requested only once per seven days. If you deposit $1,000 and have the good fortune, for instance, to run your balance up to $10,000, then it would take four separate withdrawals (which would take about a month in total) to get all of your funds.
