And this is my second swap with this group!
1 - Proofread! I offered one seed that I had 1 pack of, and 4 people dibbed it before I checked back on my Swap List and saw that I had typed in 10, not 1. I hastily turned the amount to zero, and fortunately, had enough seeds in reserve to cover the other 3 that had dibbed. But if I had not gone back to look, it could have been disastrous.
2 - I collect seeds and package them as I collect them, mostly, and they are sometimes quite different in amounts in each pack. Since I didn't want to put them as separate entries, I listed (for example) Salvia Blue Victory, one @35 and one @10. Both got claimed. No worries, sez I, I can check in Recent Events to see who had claimed first. Well, both got claimed within the same hour, within a couple of events of each other. Turned out I had enough seeds in reserve to fill up the @10 to 35, so no harm done. But still! Next time I will either have all packets uniform in amounts, or list them as separate items.
(Too soon old, too late smart!)
