This reply comes in a bit late, but it's an interesting thread I thought my comment might benefit:
Too bad about your Dauwalders experience. I have purchased from Dauwaulders and been very happy with their products and services, including their sales staff who have been very helpful. Generally, speaking, anyway.
I've ordered from them a number of times and received good products and good service, and they have their own line of binders, pages, etc. which they sell at very good prices. All on the positive side. On the other hand, I once purchased a set of lightly used binders from them on
eBay and when they arrived they had a noticeably musty smell. I emailed asking if it was possible to return them, though I was not sure I would (I'm very allergic to musty mildew smells). According to the sales person I was dealing with, the owner was very unhappy at me even making the request, claiming that they would not sell products with a musty smell.
Well, yes they would, and they did. So, I think it may be a little hit or miss with a small business where the owner's attitude sets the tone. On another day, perhaps there would have been a different result. Not the biggest deal in the world, of course.
I kept the binders and was able by leaving them in the sun on a hot sunny day, to kill the mildew successfully, so ultimately no problem.
Ordering standard products -- binders, pages, and so on -- you will not have any problem. I order from them occasionally.
In any case, I wonder why you didn't just return the kiloware promptly? I certainly would have, whether they agreed to take it back or not. The point would be to show them how it arrived.
Here's what may have happened (and this is purely guesswork): I imagine they open up large plastic bags like garbage bags, perhaps putting them into garbage cans, and pour into them any kiloware they receive.They may scoop out whatever amount a customer requests. Is it possible that some clueless cleaning person one day emptied their vacuum cleaner (a "hoover" to you) into this garbage bag without realizing what it was actually being used for?
That they refused to believe you is extremely unfortunate and poor customer service. In a bigger organization, you'd have other people to help you with your problem.
As for your stamps, they are all ordinary U.S. "regular" issues cancelled at major post offices or mail sorting facilities ("stations"), most in New York City, some perhaps connected to railroad stations, but not necessarily. Madison Square Station, Church Street Annex, Fordham Station, Bronx, etc. are all in New York City. "Station" is just the name of the postal "station" where mail is serviced, not necessarily a post office for the public, and not necessarily railroad-related, but sometimes. "Station N" and "Station H," etc. are postal stations for servicing mail, as well.
