Looking for help on Bookish first

If any of you are on BookishFirst , do you know if when there is a raffle for a book and they will send the first 2 books in the series as well to the winners. 

Will you also get all three books if you claim it with your points? 

I think you would because I think they just add your name to the list for publishers I would assume but I'm not 100% sure and thought maybe someone knows. And it be silly to use my points for a book when I didn't read the first two book, which BTW are on my TBR anyway. well the first is . 

Any thoughts and help welcome :D 

 

Thank you :)
