Will you do it for twenty (euros)?
'Me lo fa' — very quick in natural speech: 'me-lo-FA'. Stress only on 'fa'. The first three words almost merge.
Making a concrete counter-offer. The most effective bargaining technique — name your price clearly. Works best when your offer is 20-30% below the asking price.
'Me lo fa a venti' = will you do it for me at twenty. 'Me' (for me) + 'lo' (it) + 'fa' (do/make). 'A venti' = at twenty (euros). This structure is the standard Italian price negotiation formula.
Me lo dà a quindici?
Will you give it to me for fifteen?
'Dare' instead of 'fare' — 'me lo dà' = will you give it to me at...
Facciamo trenta?
Shall we say thirty?
'Facciamo' = let's make/shall we — collaborative phrasing
Posso offrirle ventidue?
Can I offer you twenty-two?
Most polite — 'offrire' frames it as an offer, not a demand
'Affare fatto' (done deal) seals a bargain at an Italian market. The handshake that follows is genuine — Italian market vendors are proud of their word. Once agreed, the price doesn't change. Never agree and then try to lower further.
