I'm reaching out to get a clearer understanding of the various payment options available for our potential order. It's important for us to know all the accepted methods, including any possible terms and conditions that might apply. Additionally, could you please provide insights on the timeline for processing payments? Understanding any relevant fees or requirements associated with different payment methods would also be greatly appreciated. This info will help us make informed decisions moving forward. Thanks!
