We're exploring options for Thermal Receipt Paper Rolls and would like to get a detailed quote from you. Specifically, we need to know the unit price per roll and if there are any bulk discounts available for larger orders. It would also be helpful if you could clarify whether the prices include sales tax or if they're exclusive of it. Additionally, please provide an estimated delivery timeframe once we place an order and outline your payment terms, as we typically operate on Net 30. Ensure that the quote is firm and has a specified expiration date. Looking forward to your prompt response!
