On CPSC.gov you can sign up to get
recall alerts if the agency takes action on a product.
CPSC officials also suggest filling out the product registration card that comes with products, or registering on the manufacturer's website. That way the manufacturer knows how to reach you if the product you bought is recalled.
Unless there's a recall companies can make the consumer pay for shipping to get consideration for a replacement or refund.
You can also reach the Consumer Product Safety Commission by phone: (800) 638-2772.
