"It comes with a price"

"It comes with a price"
 

In American English, we say "it comes with a price" usually with negative implications to mean that something is done or achieved with some sort of undesirable cost or consequence.

Is there a expression in Spanish that conveys the same?

(pero) eso tiene un costo

... trae un costo aparejado

"aparejado"... interesting ... "it comes with a coupled/attached cost"

Viene con premio is used widely in Spain

But... sometimes, "viene con premio" means something different.
For example: "María se casa con 'premio'" means "María is pregnant".

My grandmother sometimes says things like that.

I forgot the usual phrases are

eso tiene un costo
pero eso (tiene su costo / trae un costo aparejado)
