Hi! I think it's a good project.

I'm not very tech-savvy; I've never bought or sold on Amazon, but I have used Mercado Libre. It's a platform that originated in Argentina and also operates in other countries in the region.

For example, in Venezuela it works well, but resolving complaints is complicated, especially due to the return shipping costs.

In Argentina, the service is excellent, and I haven't had any problems. The Mercado Pago platform is used by all businesses and individuals to transfer pesos and is very efficient. They aspire to become a bank, although for practical purposes, I think they already are.

I hope my comment is helpful; I'll vote for your proposal later. Good luck.
