I'd take it. Like everybody else has been saying, manga tends to cost quite a bit, not to mention occasional spotty translations, so leaving manga out for recycling like that is a foreign concept. I don't even see people leaving novels and other book...
;o; Too many to choose from. I liked too many too. I'd have to split it up into several categories to name my favourite series. ...Though if I had to throw it out there, I think it may be Arakawa Under the Bridge.
Depending on location, the time it'd take to disappear would vary. Either way, it'd be stolen quicker than you can say 'Dude where's my iPad?' Have you checked your garden for kappa? I hear the love cucumbers.
I keep all the boxes and stuff for Figmas and gundam models. Makes for easy packing, and the boxes are nice. Not keen on the packaging for memory sticks. Big wad of plastic with a stick a tenth of the size in it. :/
