Ordering LuLu editorial services is no different than paying an actual editor except finding your own editor will allow you to know their names and you can check their credentials. With LuLu editors, you will NOT know who it is and you must trust that LuLu only hires great people.
And no matter how many mistakes they miss, you will not get another reading unless you pay again for the edit.
This is normal for normal publishing routes that simply get you in the door of an agent or a publisher, but then when a publisher decides to print your book it can take up to five different edits to get everything correct. You do not get this when you self publish. You will not have a copyeditor on staff to help with tiny details.
Self publishing with LuLu means you must be or find a good copy editor on your own! Even if you use the full service packages!!!
