Not to mention that someone needs to tell him that a "bid" is not the same as a "deposit".
In a bid you say of the amount of money you are willing/able to spend on a certain project or item. You, however, do not have to PAY said bid unless you are chosen.
A deposit, on the other hand IS paid out in advance in order to hold a place or item or as insurance against you destroying something that doesn't belong to you or as a way of insuring you return an item which might otherwise cost the manufacturer money. Some deposits are refundable, some are partially refundable and others are non-refundable.
