Suggestion: submit an order including both first choice and second choice varieties. Last year I missed some of my first choice [not enough donations or high demand] but got most of the second choice. By submitting both up front it should speed up the process of having to contact you saying more selections are needed due to demand or whatever. The second choice list could also be useful for any bonus distributions.
There is also the possibility of an additional sale of "leftovers" to be on the lookout for.
