I have a stack of bootlegs when i went through a stage of buying them many years back.
Boring Days In Paradise cost me around £16 but this was during the American Idiot hype where everything was over inflated.
Teenage Rampage cost me about £7 that was a year before American Idiot. So that seem's more realistic.
I've been considering selling my bootlegs for a little while as well i don't listen to them any more, it's a never ending list so the collection isn't close to being complete. (Whereas my singles collection up until the trilogy is closer to completion, it's missing a bit but 80+ cd's in a stack looks decent enough ).
I'm not really sure where your best place would be to sell. If you ask Andres nicely, he might allow you to sell to a fan on here. I don't think Ebay will be the best place anymore, unless you want to hold on them for a few months and hope that when the tour starts up, the media hype will be going around so you get a better price.
