I don't mind if there's a delay, but I want to know when I will get the item. I've bought 3 items off BC so far, and they have all gone smoothly, but, I have always had to request a delivery date, rather than being told "you should have it ...." or then "sorry, there's been a delay, you will have it....". I don't think you can expect business-like service from a public forum like this.
Some of us will make more, or less effort, but our perceptions are all different too, so someone who thinks they're a great seller, may be a crap one!
