Building the headers takes time, sending them for coating takes time, waiting for materials takes time. Learn to be a bit patient. They have been making these things for some time now, and no one has been disappointed yet. You were ALL warned in the beginning that the wait time would be a MINIMUM of 3 weeks, probably more. Complaining about the headers not being on your doorstep within a week is not going to do anyone any good. It takes 3 weeks to make one of these headers and get it to someone's door. It takes even longer if there are wait times for materials, cutting the flanges, delays with the coating, or just a big number of orders. Plus, on top of that, no matter how much you all feel like you should be their only priority, you are not the only business they are getting, and they can't just turn away all their other customers, just because you guys feel like you gathered a big group and spent a lot of money.
And on top of all that, you guys expect them to answer 8 million dozen e-mails and phone calls a day from you guys begging to sneak your order to the front of the line, instead of them actually getting work done.
Well, I doubt they will ever want to make a deal with this forum again, and seeing how most of you are acting/thinking, I would recommend you never participate in a group buy again. I've been in MUCH bigger ones with MUCH more uncertainty. You aren't going to get screwed, 6000-10000 isn't a lot of money when you have a business to run, overhead and material costs. There are little burger joints that take in more money than that in less time. I used to sell that much in tires and oil every couple days, not to mention charging for actual work on vehicles or parts sales, and that was in a little two man truck shop.
Just relax.
