For those that are new, a small reality check might be in order.
1. USDA/UC Davis operates on a very, very minimal staff. Often that precludes them from being timely in their responses. Much of the grunt work, including packing and shipping is done as a sort of "community service" by students at UC Davis, for no $, Sort of a "no-credit" lab class.
2. Every time you change, amend, add-to your order, etc. you multiply the amount of time it takes to process your order. Time is not something they have excess of. When you send your order in doesn't matter, as long as it is before December 1st. Sending in in first doesn't get you the first shipment.
3. They are there as a germplasm repository and research facility. Technically, they only send material to researchers. When we ask for cuttings, we are a retail customer, which, strictly speaking, is not there mission and purpose. So, the fact that they do ship to us is a courtesy and a privilege.
