At the end of the day, sure… in theory keeping the prices in the post for the sake of transparency probably isn’t the worst thing, but overall futile IMO. As a few people have mentioned, yoyo prices fluctuate like CRAZY, and even going through some of the posts that DO have prices still listed can be WILDLY inaccurate or all over the place based on current market value. Take the Summit for example, it’s the best example I can think of off the top of my head right now. I’ve seen (and as an owner of 4 Summits, have purchased them at) all kinds of prices over the years. $50, 60. $100. $150. $250. So much depends on color, condition, and what the market is feeling at that particular moment. So sure, leave the price up I guess… but it’s not gonna do a whole lot lol. As someone in this hobby for 15+ years, people are gonna buy and sell at whatever the hell price they feel comfortable with in the moment.
As a number of people have noted here the price is what people are willing to pay and how bad they want one. And the asking price, as well as the selling price, will vary all over the map.
In the end there is no Kelley’s Blue Book for yoyos… 
Anyone interested in a shutter for only $10,000? sidenote: I once a sold shutter for $18,888 USD but I deleted the price and marked as sold
Does it vibe?
No, it fluctuates
The reason there’s no blue book or expected value and things fluctuate is because finding historical info on value is asking the community of pulling a number out of your butt… it’s a self fulfilling prophecy. It’s is an issue because there’s no way to know what something has been valued in the past.
eBay has in many ways made pawn shops more standardized and less random because folks can just look up what something has sold before and what expected value should be. Before that it was the Wild West of idk what this is worth there for its worth whatever my heart tells me and the buyer is willing to pay.,
In the end the lack of info make the YoYo buying second hand market always a sellers market and put buyers at a disadvantage and that I think is what folks are gripping about here. Other established trading and collecting communities have setup much more buyer friendly rules to ensure more equity in trades and sales and YoYo is still the Wild West and very frustrating and trust driven as a hobby and community which especially for a new player is off putting if your trying to get into the hobby and have no idea what something you want should be valued at then later find it being sold for much less by someone else.
There also some evidence that the yoyo bst being the way it is today contributes to the waves of interest and ability to buy stuff in the community leading to periods of stagnation. This can be supported by buying habits of people during economic stressful times being atypical in hobby’s. IE people buy more things as distractions when stressed even if it contributes to said stress.
Now the one saving grace of the YoYo community and what keeps most of this outdated way of doing things working is the community’s very strange but refreshing level of perceived trust and willingness and culture to giveback unconditional. People are constantly doing things in the community yo give back to others spending time money and resources to help their fellow players, give away cool stuff without getting anything in return and generally spreading awesome and good will without and expectation of reciprocation. This is rare in general now days and even more so in collector and trading communities which I think is one of the most charming parts of this hobby. I have no clue what contributes to that culture but goodwill is really the only thing that keeps the current yoyo BST tolerable in my opinion…
As Cap Rogers said about pawn shops and eBay is the general idea here. Having a history will reign in the wild variations because of expected sale prices. Just because prices vary doesn’t mean we shouldn’t be able to keep listed prices. The whole argument against it is just a non sequitur.
Also even with all the dissenting comments the most liked comments are the ones that support the idea of keeping listed prices. This really should be a rule.
i own many business and do six figure in exclusive online sale, been through many audit in multiple country of operations
you are not getting your yoyo forum posts audited from IRS haha, do not worry.
Not that it changes all that much, but selling used goods at a loss like you mentioned is not considered taxable income. And you have to hit a significant profit for it to become an issue tax wise. Also getting audited for maybe $1k of profits over a year (and thats mad generous) isnt going to happen
I understand the worry of it becoming more business and less community building, but i dont really see how not deleting the listed price from the bst post really makes that happen.
