I completely understand if you don't want to buy from eBay Nicole, but I agree with Marianne: many sellers purchase items in bulk and resell them via eBay, and this stuff is brand new.
If you should reconsider, I'd go for the new items with tags attached and have a look at the seller's history first.
I forgot to mention the sites you were asking about. Sometimes I use
- smartbargains.com
- bizrate.com
- yahoo.com (first click on 'Shopping' directly underneath the word Yahoo! in the middle of the screen, then enter your search term)
But I find that they often all yield the same results (I did find a few Fantasie bras, but they were all as or more expensive than on Bare Necessities).
Often you just have to do an individual search (i.e. type in your search term in a search engine and browse through the results, which can be time-consuming...).
