"There are rumors that the Babies R Us stores will give you store creditfor used BPA bottles because it is a safety hazard. Each store can set its own policy regarding this issue.
I called one of our local stores. Their policy is that if you were registered at Babies R Us, or have a receipt for bottles, they will offer store credit towards trading in your BPA bottles for different bottles. Other stores don't require a receipt at all - call ahead to see where you can get the best deal. I bet few if any moms have the receipts for bottles. Sheesh, I can't even find my keys."
You and me both, sister. I don't have any baby bottles in the house anymore, but if I did I certainly wouldn't be able to find any receipts.
Let me make a shameless plug for you to buy high-quality aluminum (coated with an inert lining material) sport-top SIGG bottles from Amazon.com or ReusableBags.com*. They're expensive, but they last forever, and are safer than nalgene.
Use the comments section to post if the BRU in your area is taking back BPA bottles or not.
* If you buy through Amazon I get some cash on your purchase. But if you buy from ReusableBags.com you're buying from a smaller business, plus you can buy the Riesenthal bags that are so gorgeous I'd lick them if I could.
