Last year, I came on board about a week before the list came out. I had no clue about all the different cultivars. The list totally overwhelmed me. After some quick research, I picked out about 10 different cultivars and had my order in before the end of the 3 day window mentioned above, so it would be considered as day one. I got about half of those I requested. So yes, they do go fast.
A few weeks later, a very generous member (Kerry), gave me nearly everything else I had on my wish list.
I'm much more prepared this year. Have my list ready. I just need the inventory codes.
