Why buy/sell models?

Question

css

Hello! Please tell me how to estimate the cost of a model for games !? (architecture, interiors, props and other statics)
And how not to buy a model that costs more than it should?
Are there any measures by which the cost of the model is determined, so as not to create "Dumping"!

Answer 1

replace padding with margin

Answer 2

obviously, there is not enough space for the text to be in one line, span / div has nothing to do with it.
you can do

.bonus_packege{
white-space: nowrap;
}

and then the text will stop wrapping at all

Answer 3

You can see here for what money models sell, from here and estimate the price for your own.

Also, assets with models are sold in the Unity store, you can ask the price there.
