Basschat doesn't owe anyone a sale. I know TheGreek is barely the most guilty party in this respect, but it needs saying - we've seen a few of these threads now, and it wants saying. There are no guarantees.
I like the analogy of BC as a great shop window. But the thing with shop windows is that people will window shop - and it's all the more easier to do so, at a remove, online. People will browse; they will admire; and they will make queries, which might not well translate into sales. There's a little bit of tough love here, but if you don't like it, don't list. You'll anatagonise yourself.
So, a quick bit of 'homework' could dig out all the information online? Oh aye, because - with the bass in your own hands - it would have taken you an age to add the extra detail to your ad? Or some decent pictures? Or some sound? Or an opinion on the nature of the bass?
I think sellers - myself included - should simply have more patience and more pragmatism in our expectations. Yes, there are some genuinely poor examples of buyer behaviour, but I sometimes wonder if we're not our own worst enemies, thinking more generally.
However, enough with the generalisms. I've wanted a grumble about complaining sellers for a while, so I'd thank TheGreek for the opportunity
So: deep breaths. Then deeper breaths. I'm sure you'll have luck in the end, but be honest about when items will go and what for; look at other routes to market; perhaps be more discerning with who you deal with; and I wish you all the best in getting your sales completed.
