Heritage White Egyptian Walking Onions

Hi all. I have the regular red walking onion, but I'm looking for the heritage white variety for a more sweet onion option. Most places won't ship until fall but I'd like to go ahead and get some and get them going.  I'm in zone 8a and I've never had an issue getting them started at any time of the year. Southern Exposure, Planting Justice, and the EgyptianWalkingOnion.com website I found all won't ship until fall. If you have resources or are willing to trade, I'm game!
