¿Cuánto pide por esto?
CHIE-de — Dos sílabas; 'chi' is a hard 'k' sound before 'i' — as in 'key'. acento en la primera sílaba.
Usa esta frase as your first question when you pick up or point to an item and want to know the price. It is more natural at a market than 'quanto costa?' because 'chiede' acknowledges the seller is setting a price.
'Chiede' is the formal third-person singular of chiedere (to ask). So 'quanto chiede' = 'how much do you ask'. Esto es the standard antique market price inquiry — it implies you're open to negotiation, which is expected. At a fixed-price shop you would say 'quanto costa?'
Qual è il prezzo di questo?
¿Cuál es el precio de esto?
More neutral — doesn't imply negotiation as strongly
Quanto vuole per questo?
¿Cuánto quiere por esto?
'Vuole' (you want) — very natural at a flea market
C'è un cartellino del prezzo?
¿Tiene una etiqueta de precio?
Asking if the price is already labelled — often it is not
Italian antique markets (mercati dell'antiquariato) are cherished weekend institutions. The most famous is the Porta Portese market in Rome, held every Sunday since 1945. Others include Il Balon in Turin and the Fiera di Sinigallia in Milan. Bargaining is expected and part of the pleasure.
