Here's the follow up from 3R Plastics: I received a call back from Diana at 3R Plastics yesterday and she notified me that they will do a run on the O gauge plastic ties real soon, and that these will only be available through Amazon. I said there may be several folks on this forum who might be interested...just in time for the holidays! If interested, I would check the availability from Amazon in a few weeks. She also said she found one bag and would allow me to purchase this directly...which I did. Santa came early!
Hope this helps those who are interested.
