A non-profit -- with which I've been affiliated -- asked me for suggestions as to how to expand their income stream by selling kit online (in addition to locally). They're interest was in trying to understand how it has fared in the past.
[They've tried many times to do this -- usually with little success]
The items they are selling have very low acquisition costs (most are simply donated). And, much of the processing labor is gifted.
I stress these facts to them and they have habitually (over the years) ignored them -- instead, trying to determine "market prices" for their items (and then wondering why they aren't selling!)
At times, in the past, the person(s) responsible for online sales have been paid a commission (a mistake, IMO -- *I* don't get paid for the efforts *I* donate so why should they?). This, I think, causes them to drive the asking prices up as it maximizes their "take".
Of course, if you're not selling anything, then you'll quickly decide not to waste your time on this "volunteer" endeavor (i.e., if NOT paid, they would be doing it because they wanted to gift their time instead of make some money!)
My thinking has always been: "what will you recover from the item (and what 'processing' will be required to do so)? Pick a figure some epsilon above that and you're ahead of the game!"
For example, a surplus PC is worth about $10 -- after you've disassembled it into the recyclable components (which uses time from volunteers -- and floorspace for them to do it!)
A disk drive is worth $0.50/pound -- regardless of capacity or working state.
Cables about $0.10 -- again, regardless of their original use.
So, selling an HDMI cable (often in original packaging) for $1 is a huge (percentage) profit -- even if only a dollar or so.
But, selling $1 items that require shipping makes them quickly expensive. So, sell MORE in a lot! (But, how many people want to buy a dozen HDMI cables for $10? Plus shipping)
Items with greater intrinsic value tend to be heavier (who wants to ship an 80 pound server? and who's going to crate/package it for shipping with the assurance that it will arrive intact -- lest the purchaser gripe about a broken item)
But, more valuable items tend to require some verification of their integrity. You're not going to want to purchase a tablet that is locked. Or, that has a battery that can't hold a charge. Or, that someone has rooted into some bizarre state.
So, you need someone to assess their suitability for sale/reuse. (Those "someones" are few and far between. Spending a lot of time on *one* item when you can make a bigger impact on dozens)
Add a commission structure atop this and it just drives sell prices up. Which makes it less worth the "volunteer's" time.
The easy items to reuse/resell are things like cables, disk sleds, wheelchair wheels/casters, etc. Things that have few moving parts or non-obvious ways of being damaged.
THEN, you have to not be mercenary about pricing -- some large discount off of other items that you are competing with else you'll just be another of the listings that never sells!
Any ideas as to other items or strategies to help them "move" kit? Remember, moving it to the recycler is an out-of-sight-out-of-mind activity -- no need to store it somewhere WHILE waiting for its disposition. Nor fear of someone opting to dispose of it thinking it's recyclable.
How do *individuals* who sell deal with this? It's likely a "side gig" and one that you don't want to put much time or effort into...
