The thing about eBay wigs is what you see in photos is not always what you'll get. Those eBay wigs tend to be quite thin. There are some better eBay stores, and reviews on this site, but those wigs will cost you closer to $30-40. The last option is to find a second-hand wig in the Marketplace. You might be able to find a high quality wig for a lot less money. I'm trying to get rid of this Enchantment wig
for $25 (mine is natural black). Best of luck!
