I used to hoard my boxes too when I got them from something I ordered online. I would cut the tape off the flaps so I could flatten them out and stack them in a plastic tote I have my boxes stored in. From time to time I'll go thru them and discard some but I like to keep some to mail quilts in. Just tossed a whole trash can full last night so I feel good. Also climbed up into my garage rafters to see what I had stored up there. Found a plastic tote full of empty cartons from numerous computer items. Went thru them and tossed those I no longer have and/or replaced with a new item. Like to keep the box stuff came in in case I decide to sell it online or in a garage sale. Looks better to me if I have the box. Still have the original boxes all my sewing/embroidery machines came in too up in the rafters. Found a computer scanner in one of the totes I'd forgot I had. Thought I'd given that away.
