Vertimas - Portugalų (Brazilija)-Anglų - Boa tarde, gostaria de saber como fazer contato...

Hi ArenaL5

I have made some minor changes so that this text reads more natural in English.
Your original translation is below.

Good afternoon, I would wish to know contact information to buy products. I request the price for each item below.

I have set a poll to get other people's opinion and suggestions

Thank you I like your version better, actually.

If my opinion gets to vote, where is the poll?

Hello

I had set a poll, and got some positive votes, so I have validated (approved) the translation, that is why you couldn't see the poll

Ah, okay.

By the way, can you change the title too?

Done
