Price of Derby blades going up?

[Taborcarn]

I've been watching the price of these on Amazon, and over the past few days a pack of 100 had risen about $2.00. It wasn't all at once either, the price is creeping up 10 or 20 cents at a time, several times a day. Does this seem strange to anyone else?
The 200-pack also went from $12 to over $20.

Bestshave.net still sells them for $7.75 per 100.

Yeah I think that's what they used to be... I wonder if there's a supply issue? Or maybe it's just Amazon being weird.

I ordered 400 a couple of weeks ago bringing my derby count up to 1300.. I hope it goes back down so I can order some more..

I grabbed 100 last week, when they were still $7.50. At two dollars more, I'd go for Astras.

i hope this isn't the case with all DE blades now, especially the blades I want. I was able to snag a 100pk of Derbys off the BST for $5 shipped. no way i could pass that up. i'm very grateful!
