Are you in need of an "expensive" gift for a lady? Amazon.com has quite a lot of their jewelry on markdown up to 70%. Just go on their website, go to the jewelry section, and click on the On Sale Now tab in the upper right-hand corner. There are pearl necklace/earrings/bracelet sets for $9.99, sterling silver rings for under $10---and of course jewelry for much more. The pearl sets would make a nice gift for someone's mother or grandmother. I found a couple of really cute silver rings for my daughters.
The only thing you want to watch is that since many of the items are sold by outside vendors, shipping charges do apply. The ones I looked at were very reasonable, though, and at least one vendor (Peora) offers free shipping anywhere in the U.S.
