Turnips Anyone have good odds of a spike this week?

[Grindellion]

Just bought about 4 million's worth of Turnips, and I'm fairly sure this week could be a spike for me, but I'm unsure. So, if anyone tracks their prices and has a good shot of a spike(or if this is read the week proper and has a good price), it'd be real cool if you could let me know, and we could work things out from there. I figure it's better to post early over late on something like this. Thanks!

Edit: My luck ended up coming through for me, got a Large Spike on Wednesday PM.
