How to sell in the classifieds - I don't want to overdo this

[DGM]

I have a number of HP, TI, Casio and other items I want to sell. I wonder if I should put them all into one thing, split them up by brand, or do something else?

The items include things that work, things that don't work, things that might work, a few books, and accessories - about 70-90 items in all. I took (good-ish) photos of most of them.

One thing - anything that does not sell goes to a landfill - I have to get rid of things. Also, I prefer to deal within the US (and Canada) for postage reasons.
