Does LuLu Charge you a $35 Isbn number so they become your publisher?

So then if you wanted to upload your book as an eBook onto Amazon / Barnes and Nobles you can't?|||I'm not sure about Lulu, but I know Createspace (run by Amazon), allows you the option of either getting your own ISBN OR they'll assign you one for free, but you wouldn't be able to use their ISBN if you intended to submit your story to another publisher or another self-publishing gig. I think they'll allow you to use it for an eStore, though.
