I sell ONLY at farmers market and sell yellow and red onions. The reds do not sell as well. Approximately 1 red to 10 yellow, as green onions, but as large later onions it's more like 3 red to 1 yellow/white. Good luck, our market doesn't price the organic any higher than conventional.

I sell red and yellow storage onions for $3 a pound at farmers markets and my store. The heirloom sweet onions I sell for $2 a pound for the large and $3 for a 1 pound box of the smaller ones. Scallions I sell for $1 for a bunch of 5 large.

i find the red and yellows do not sell well in summer mainly because everyone uncuts my in price. but that is okay as I grow them to sell through the fall, winter and spring after all the other growers in my area have run out of onions
