online source for wool diaper cover multi packs?
 

My wife sent me in search of some wool diaper covers today, and all I
can find are single ones for $15 to $20 each on Ebay. I figured they
would be in the $5 to $7 range each in multi packs, but so far have not
been able to find anything like this.

I obviously don't want to buy them one at a time, plus pay postage on
each and every single one.

Can someone tell me where you have found a deal on these? Thanks!
