how best to sell used sets of lego?

[cluttered]

DS has outgrown his themed lego sets, some of which were quite expensive. They will have all or nearly all of the pieces but we haven't kept any of the boxes, not sure about the building instructions although these are available online. Just wondering if anyone knows if there is any market for these?

Most of them are presumably not available any longer or at least in the hard to find category. Mixed selections of used lego sell really well I know but not sure about kits that are in less than excellent condition, does anyone have any experience of selling these?

There is a market for Lego. Just advertise each set as it is. If it has pieces missing or is missing the instructions you must say so. They will sell, I'm sure, but be flexible with your expectations re price.

cluttered we are always after lego, happy for you to PM me

Any starwars or Lego city sell it to me!!

Make it up according to instructions online.
Take photos. State original instructions not included but available online. No box etc. Bag up in ziplock sandwich bags.

Sell ( hopefully)

Before eBay may be worth trying local paper.

or sell on here too - lots of people aren't aware there is a place to sell on MN. It costs ten pounds per year but no fees after that - I sell allsorts, clothes, toys, prams etc and people always pay you gifted paypal so no fees there either
