My schedule's really tight at the moment, so not sure I can get over to the warehouse this week.
In the meantime, call the lovely folks at
Mouse Shoppe. They have ears listed for $4.99 each, but you might be able to work out a deal on quantity.
If that won't work out for you, let me know, and I'll see about sending Ken over on Thursday night after he gets off work. I can give you my WF account number to drop funds. We'd be able to ship them on Saturday - we'll be at the park all day on Friday.
