Hi there,
If you get no takers, rather than ditch them, contact one of the many ebay magazines sellers and sell your mags to them. I had about 70-80 mags to get rid of some years ago. A guy made a sizeable trip to my house to buy them all. I got about £100 for them. Of course they would go and offer them on ebay for £4.99 or whatever but everyone was happy.
Cheers
David
