Some places give you a discount if you buy things on Pix. Buying on CC is kinda an illusion.

It's more worth to buy things with Pix, and use things like Inter/Meliuz to use 10%~ cashback on stores...

(of course, if you don't want to use insurance or installments).

Btw, my father produce furniture and industrial products, and we always make the price clear to the customer, including what the price would be depending on the payment method. It might not be ideal, but… we prefer to give the transparency to the clients. Because of this, I do say 90% of the clients these days pay only with Pix. A few years ago it was all CC or debit cards.
