Car Boot Stuff (Parkstone, Poole, BH14)

I'm having a clear out and I will have too much stuff to list everything separately
Does anyone do car boots or anything like that?
I will be doing this clear out for the next few weeks/months as I have amassed too much clutter
 I can just take it all to a charity shop but you know how choosy they are they will throw most away which would be a shame
