It was one thing for ABU to stock Rearz when they had no equivalent product, but now that they have Space and Little Pawz, I really can't see them doing it. They'd be compromising the target market for their own product.
My conclusion is the only way to get these into North America is to buy a bulk amount from ABDL factory to bring down the price per unit. Still can't really get it below 2.50 (USD) per diaper but thats the price I'm definitely willing to pay for some EU stock to my stash.
Littles-downunder.com.au will have Rearz Safari in stick around 10 January - obviously for Australian customers - and others that want to pay international shipping!
