I've got about 230 studio cables that I'm about to put up for sale on Craigslist (including 57 Monster cables, 138 Hosa, and various makes for the rest like ProCo or Neutrik).  The bulk of the cables were used to wire my fully balanced studio, then there are plenty of others for all the things you need like instrument cables, MIDI cables, microphone cables, speaker cables, etc.  
 
I wasted a lot of time yesterday and went through each of the 72 types to determine what it would currently cost to buy one of that type (where a type is the combination of the connectors, length and make).  So now I have individual values for each cable.  Note that some of the cables are considered "Legacy" cables so the current price is actually a used price.  Also take into account that everyone knows Monster cables are always over priced.
 
So, here's the question:
 
What percentage of the current values do you think I should put into the ads?  40%?  33%?  Higher?  Lower?
 
TIA!

Bulk lot? Are they all tested/working (and are you advertising them as such)? Clean/like new (as in no bar grime like you'd get from patch cables you'd drag to a gig)? How quickly are you trying to sell them? Are they individually sorted/tied?
 
I used to do surplus electronics stuff so without actually seeing or handling the lot I gotta ask to get an idea.
 
Of course a bulk lot is a lot easier but if you have them individually sorted/tested and they are in good condition or whatever the price goes WAY up. You may be better off selling smaller lots of cables by type or even individually but it sounds like you just want them gone.
 
Anyway... more info needed.

+1 to beep, exactly my thoughts

In the meantime it is all about presentation. You increase the price people are willing to pay by simply wrapping (and if necessarily cleaning) them properly. Testing them makes the price go up WAY more (which is unnecessary if you already know they work and are problem free).
 
If you have not already you could head down to the hardware/garden store and snag one of those small spools of plastic coated twist ties. Wrap the cables nicely and twist them off. That simple act can add a buck or two (or ten depending on the cable). If you can tell people it works and it's not all covered in shmootz you can easily get 50%.
 
The people that buy cables usually NEED those cables and if they can get something that is (or looks) almost new for less they'll drop the coin.
 
Bulk lots, especially messy ones... you gonna get raped.

125%. Call them vintage.

Very good to new condition.  NEVER gigged with (these are from my home studio) and they all work.  They are all wrapped nicely (roadie wrapped of course!). I'll post a picture or two in a bit (need to take some).
 
(50% easily?  Daaaaaaammmmmnnnnn!  That would be nice!)

Depending on the cable that's actually lowball for proprietary cables... and yes, I have gotten above market/new prices for cabling.
 
Not sure what the surplus scene is like in Washington state (I'm assuming pretty good which works against you) but sometimes the "I gotta HAVE IT!" impulse reaction can triple selling price or more.
 
Rare cabling? Fuggedaboutit. I would have paid a millionty % markup for the old Ampig cable connector that allowed me to use my old cab (but not a jillionty % because that would just be silly).
 
This does not work with bulk lots though. Separate out the weird stuff is what I'm saying and maybe put it on ebay or hunt down online electronic distro sites. They may give you a better bulk price if you have something crazy cool in the lot.

Oh, dude. If that's the case AND you provide a detailed list (be sure to say "like new/only used in clean pro studio" or some such) then definitely list at 50% OBO. Some hound will snag them. Christ... I kind of want them. I LOVE having mountains of cables around for sheer convenience. Sadly my collection has dwindled.
 
lol
 
Edit: You should still maybe yank out the proprietary stuff and ebay those buggers or split the lot out if you have time to wait for sales. That is however more time and a bulk lot is much easier to just get the frack out of the house. Sometimes electronics customers (especially from Cragslist) make wrangling with it all more annoyance than the extra few bucks is worth. One good buyer for less might be the better option in the long run.
 
Good luck.

 
 
I think Comcast has a sale on their Cable service. But if you call and complain you can probably even get them to go lower.

I'm gonna offer one more bit of advice before getting back to "work".
 
You may be better off separating out all the "Monster" stuff and other fancy froo name brand cabling from the rest and selling it in two separate lots.
 
Obviously most of us here know that name brand matters not (at least for the markup). So let's say you have a 50/50% mix of Monster cables vs. other working stuff.
 
The people who don't give a frack about the name but are aware of the ridiculous markup may avoid your lot because of the markup (because you are basing this of new prices so 50% of insanely overpriced is still overpriced). The other people who are willing to pay markup for name brand aren't going to appreciate the other stuff as much.
 
So you split it out and sell the Monster lot to those who give a frack abotu such things and then the rest to those who just want the bloody cables (and may actually be turned off by the mere mention of Monster and the like).
 
You speed up the sales and probably maximize profits. You may also get the added benefit of a little social experiment of who responds to which lot. I'm willing to be there will be a stark contrast.
 
Cheers.
