If you refused to throw away your favourite books as a child, and now, as an adult just sit there and stare at them collecting dust while you search your room for every spare penny you can find, you'll be pleased to know there's a dream solution out there.
That's right - those new pair of jeans you've been staring at on your phone screen are an item that could be on the way their way to you soon, and all you need to do is part with your old books.
Providing you own first editions, you might be surprised to hear that your bookshelf is storing as small fortune - with publications like Harry Potter, The Hunger Games, and The Amber Spyglass being items that could make you serious bank.
1. The Harry Potter Series
If you've been harbouring a signed set of all the books, and are up for selling the entire lot (controversial, but you do you pal) an extra £30,000 could be landing in your book within days.
For those of you who own a spare, unsigned, first edition of one of the books you could still earn a fair whack out of putting it up for sale - not 30 grand, mind - but more than enough to make your decision worthwhile. The Prisoner of Azkaban, for example, is going for £75 on eBay.
2. His Dark Materials by Philip Pullman
Great news if you were around in 1995 and managed to get your tiny baby hands on a copy of the Northern Lights - because that copy will make you almost £500. Even if your copies aren't first edition, you can still make a tidy profit - with this copy of The Amber Spyglass going for £50.
3. The Hunger Games by Suzanne Collins
Even though The Hunger Games is hardly retro, first editions are still surprisingly popular with collectors - with the whole set being priced at £380 on eBay. Pretty neat.
4. The Cat in The Hat by Dr. Suess
This childhood classic will make you enough for a nice shopping splurge (IF you're prepared to part with it) with the first edition going for around £58 on several online retailers.
5. The Wizard of Oz by L Frank Baum
Bit of a longshot, but if you grandparents were massive fans of The Wizard of Oz and have an old first edition knocking around, let them in on the fact that copies are selling for £2500 on eBay. That's enough for a lifetime supply of M&S cardigans.
