Stock manager for medium sized business ordering thousands of pounds of stock per week, i use multiple suppliers but broadband buyer are the only ones who let me place an order for next day delivery and then advise afterwards they've moved the cut off for the day and my order wont be next day, if this was communicated when i tried to place the order i could go elsewhere as some deliveries are time critical. good prices but cant be relied upon to deliver as agreed
