That will probably be the fastest way to know when they are available.
Alternatively you can order all the components individually since everything else looks available, except the hardware, and source the hardware locally. But that will be more legwork on your side since you will have to make sure you order the correct quantities of everything.
I am waiting on idlers and pulleys, they should have shipped by now. The rest of the next batch is packed and ready.
But yesterday afternoon I have a few kits left. If they are all gone now I will take my other inventory of idlers and pulleys and make up a handful of Primo’s. Hit that notification box, and it will let you know when I get it done.
That is one thing I absolutely hate. I placed a large order the other day, they agreed, and took my money. Said they shipped 80 out of 480, the rest would ship “at another time”. I was heated, absolutely heated, it was a very significant amount of money and they told me it was on hand and ready to ship. Well it cost them several emails and a phone call. I think I have established with the owner that is shady and they made it right in the end.
Selling things you do not have on hand is a fragile way to do business. I could imagine doing preorders for something but that would be a limited run for sure and it would be very clear to all involved. I guess more of a group buy than a preorder I suppose.
