Last week Cathe said they would not finish shipping all of the replacements until the end of this week. I havent got mine yet either - but am sure I should see them soon.
Mine were in the mail box when I went home for lunch--I guess I know what I'll be doing this weekend! I'm paranoid that I'm going to end up sending back my old ones that worked fine and end up with defective new ones!
Teddygirl, I just got mine yesterday (Friday) through standard US Mail. I didn't pre-order until the end of August, so I suspect I was towards the tail end - hope that helps!
