Some are very good, some ok. Some newer, some old.
At the price, it's a no-brainer. Some come with MRR (Master Resell Licence), some have more content than just an ebook.
It could be articles, email swipes, graphics, webpages (ready-made html that you can personalize and upload).
Any questions? Please ask BEFORE you buy. Many more packs available.
