Biodom: I saw you deleted your post. As always there are "pain in the -beep-" customers and customers you like to work with. The good customer understands what he's buying, and he tries to help in the process. They get their issues solved quick (if any) because the personnel likes to work with them and they point exactly to the problem they have.
The other category keeps the vendor busy with questions, changes, options, more changes, does not regard deadlines, timelines, weekends .. they're the "customer" so if you want their business they will push you over the normal limits. As a manufacturer, you either "educate" your poor performing clients, or you drop them.
As a business, you get reviews from all over, and you struggle to keep up with demands OR you run your business decently, with strict rules for everyone. Stricter rules might seem a "bad business practice" in the beginning, but in the long run you end up having a happy life.
not sure what you referred to. I deleted a post about price because somebody already answered and this guy was satisfied, so why clutter.
I am also not sure about strict rules as far as what this referrs to, but i believe in sponds integrity, however communication about shipment queue could be better.
regarding weekend-it is currently NOT a weekend in Israel. Sunday is a working day, Fri and saturday are the weekend AFAIK.
Regarding pain-in-the butt customers-sometimes they are complaining, but buying-just look at one OP (hint-hint). He is buying from everybody: Spond, KnC, Bitmain, etc. etc and he complains about every one of them, but keeps coming back. it's much better than to have a customer who gets so offended, that they NEVER come back-just look at BFL or KnC message boards-it is epic.
