Book Box Subscritions and Out of Control TBRs

So I currently get 3 book box subscriptions, A Box of Stories which comes every other month and FairyLoot and Illumicrate which come every month.

I love my A Box of Stories box as its inexpensive and you never know what your going to get (I currently get the 2 box Fantasy box down from the 4 books Sci-Fi and Fantasy box) the only problem is some of the books really don't sound interesting and out of the 5 boxes that I've recieved so far this year I've read about 4 of the books. I have 15 books unread from A Box of Stories.

I started getting Illumicrate in May and I have had the May, June and July box. With Illumicrate they do a varity of genres so you could get YA or Adult Fantasy, Sci-Fi, Contemporary etc and I'm predomantly a YA Fantasy reader. I didn't want the book in the August box and I couldn't afford the box for September and out of all the boxes there's only been 1 book that I've read and that was May's book The book of Night by Holly Black which I really didn't enjoy, I'm unsure on Junes book We All Fall Down by Rose Szabo and I am dying to read July's book The Drowned Woods by Emily Lloyd-Jones (I just have to get through my library stack first). So I have 2 books unread from Illumicrate.

I started getting FairyLoot in May also and I have had all of the boxes so far as I prefer YA Fantasy and thats why FairyLoot does so when it came to having to only have 1 book box for September I picked FairyLoot (even though I also wanted the book that was in the Illumictare box). I have had 5 books from FairyLoot since May (June was a double book month). May's book was The Stardust Thief by Chelsea Abdullah, June's book was This Vicious Grace by Emily Thiede and Twin Crowns by Catherine Doyle and Katherine Webber, July's book was The Darkening by Sunya Maya and August's book was Violet Made of Thorns by Gina Chen but I haven't actually read any of the book even though I am looking forward to geting to The Darkening and Violet Made of Thornes. So I have 5 unread books from FairyLoot.

Altogether I have 22 unread books from book boxes, 25 if I include the 2 A Box of Story books and September's FairyLoot book which will be here sometime this month (and countless books that I already own that I haven't read yet) and even though I seem to be going through a lot of books this year (I'm currently reading book 49)

I think I really need to start reading some of the books I already own and as well as the one's I've been getting from the library and maybe cut back on book box subscritions and buying new books just so I can unhaul the books that have been on my shelf for years that I am either not going to read or that I've read and I'm not going to read again as my shelves are almost full.

How many of you are also having this trouble? Being subscribed to various book boxes but are not actually reading the books I'm curious to know.

I'm thinking of maybe cancelling my subscription with Illumicrate and just keeping FairyLoot and A Box of Stories for the rest of the year and if I'm still inthis situation in the new year cancelling the A Box of Stories box to or at least spreading the subscription out so it comes every 4 months instead of every 2.
