@ Socko – Good luck getting rid of as much clutter as you can before the move! Clutter can act like the proverbial goldfish in a new home, and grow to fill up all the new space!
There are also services you can look into that list items on eBay for you. I’ve never used one myself, but I have heard they work for people who don’t have the time to list their own items. They of course take a percentage of the money made, but it might be worth it to you just to get these items out of your home, in addition to making some money off them.

I think all of us have a little “horder” inside of us(Forgive me if spelt incorrectly)
We also have an impending move ahead & have boxes of christmas decs recently remove sitting in the lounge waiting to go into storage. We are hoping to locate to a larger house (renting for the interim) that will hold all of our “clutter”. A lot of it will be removed & those with plenty of life left in them get labelled for eBay. Most times I find that I keep forgetting about listing them therefore they sit around far too long.. until we decide again in the cycle that indeed they are to be listed on eBay! And so on…

Hey, good luck with your move later in the year!

Getting rid of the stuff you don’t need is a great start, because it gives you more room to organize all the things you do want to keep.
