Have you all been following the CPSIA story? I mentioned it briefly once before, but there have been some ongoing developments.
In the last few days, the CPSC regulators have issued some vague statements that SEEM to say that resellers (consignment stores and thrift stores) won't have to test items for resale, although they are still subject to penalties if they sell items that test positive for lead, and that children's books are not subject to the new law unless they have "play value" — like vinyl bath books. But check out this letter which calls for regulators to "hit the pause button" until all of this can be worked out … instead of having the law go into effect February 10.
However, this still doesn't take into account small Etsy-type sellers of children's clothes and toys, which is disturbing. The best overview of the problem and what you can do to help is still at Fashion Incubator. (The latest post is here.) This Etsy post is also a good place to start.
