My response had nothing to do with HOGs or "brotherhood" other than the fact that I do tend to trust established HOGs with my money more quickly than others. As far as wait time goes, however, I'd be just as inclined to give a reputable seller the benefit of doubt as I would a HOG.
I think 4-5 days is quite reasonable on shipping. If I ordered something right now from a host of my usual online vendors, I could expect shipping within 2 days from maybe a handful. In my experience, businesses can often take a week or more to ship. That's why most standard shipping details promise delivery in 8 to 10 business days, or sometimes 10 to 12 business days. An item has to be located in a warehouse, item has to be packaged, item has to be processed in a database of some sort... you get the picture.
In my own case, I've had instances (with Beckers and those big green boxes in particular) where I couldn't find a decent shipping box for a day or three. I've had instances where I was simply too busy to get to the PO for a few days. In such cases, I do update buyers as to any delay. Seems like this seller did email and said it would be Saturday before the knife could ship.
The fact is, however, when you list a knife on the Exchange, you don't know EXACTLY WHEN it's going to sell. So it's a little hard to predict just how busy you'll be or how quickly you'll be able to get to a post office when it does.
I won't make any further suppositions about the deal in question because I don't know the details. I do know a lot of GB&U threads could be avoided if people stop making assumptions and nail down details in advance. The OP here even mentions that he
assumed shipping would occur more quickly.
My take here? The world has just gotten in too dang big of a hurry. Do your homework in advance. Then slow down and take a deep breath. Unless you have a pre-established deadline, a few days is not much in the big scheme of things, and it's surely not worth the stress. Once it's been a couple of weeks and you haven't seen your knife and the seller isn't returning emails at all, then you can worry.
