No advices! Advice is always singular, no plural form and it is not countable, so a piece of advice, two pieces of advice, but NOT an advice, advices

Martin: Guys, I want to ask your advice about buying a house.  Can you give me some advice about buying a house?  I need some advice on which house to buy

Paul: I gave you a lot of advice, but I don’t think you listened

Monica: Let me give you a piece of advice, Martin. Don't buy a new house! Take my advice and rent something, instead!

Martin: Jason, can you advise me on this, too, please?

Jason: Martin, I have two pieces of advice for you about the house…
