5 days is nothing. wait, relist.
eBay: any ’watchers’? how many ’views’?
If you give us a link to your listing, perhaps specific advice, i.e. wording, will emerge from members with selling experience.
Equipment: I always consider the lowest price I would accept, then add 10%, list it as buy it now. So I can agree to a request for a discount from a potential buyer.
Buy It Now. I used to bid/spike years ago, now, I, and many others start by filtering their views as 'buy it now' only. You will miss those buyers if yours does not have a buy it now option.
LP’s: I start with minimum including shipping below $10. and let the market determine value. Same thing when I sell R2R tapes, start below $15. incl. shipping, desirable ones naturally get higher prices.
If, like me, the object is to make space, the money is nice, i.e. I just bought a nice CD player with my last 90 days of LP sales.
As for your item, if you don’t need the money soon, relisting is easy, I have 26 lps currently that have been re-listed many times, nobody wants them. I need to add some new ones. Point is, bingo, one undesirable will suddenly get purchased, just a matter of time.
Also, check what others are selling theirs for, ’watch’ others listed on eBay.
hifishark.com will show you more listings than eBay, both for sale, and prior sales, all good info.
btw, In my general notes I specifically offer ’unconditional returns’, gives buyers confidence they will receive a trouble free item.
and, state that you will double box the item.
