Boxes
I've got boxes for all types of electronic gizmo's that I keep for whenever I need to repackage them.

I imagine it would be easier to toss the boxes and buy new one when the time arises when i need them, but boxes are so cool, when everything fits perfectly.

Old Clothes
Got a ton of clothes I will n;er have the need to or the opportunity to wear ever again. Need to sack that.

Old Furniture
Could find a place that buy's antique furniture and sell them the stuff or I could just rent a dumpster and dump it.
