I've posted on this subject before, but since the links have come up again, I thought I'd share. Be wary of the "expensive" $25-50 charms. They are basically silver charms with colored metal inlaid in them. My wife bought five of them last year. Within two weeks of being home, one of the inlays had chipped in half and fallen out. We called and had a replacement shipped. Within two days of that one coming, another inlay completely fell out! Sadly, we ended up sending the whole thing back. Just my two cents on them. Some of the higher-priced Disney stuff is good quality, but only a small amount of it, IMO.
