Submission Talk: Multiple Flashes in one Document

Hello followers and fellow writers!

Instead of a traditional post, today I have a question that I hope will propt a discussion in the comments section:

When you come across publications whose guidelines say things like “Send up to three flashes in one document” or send “For flash fiction, please send three pieces, all pasted into one document,” do you usually wait until you have three? or just send one? If you send two or three, do you select pieces that are drastically different from one another? or pieces that are thematically similar? Why?

Have you eve had something accepted from this kind of submissions? If so, so they accept everything or just one story?

For a while I avoided publications that ask this because I didn’t to handle it. However, this week, I got brave and submitted a few documents containing three very different flashes and one with some thematically similar stories.  Anyways, I would love to hear about your experiences!

p.s. If you are wondering why there is a picture of zucchini on here, it is because there are multiple fruits growing on the same plant, just like multiple submissions hanging out in one document. Will they motivate the owner to care for the plant and encourage them all to grow? or will they kill each other with competition?
