I have been selling old records and initially that was going well, now they require every bit of information on the record and its label, the colour of the record etc. Most of my existing for sale records now have to be re-written.
I am getting around it but every day, this all takes a lot longer. Buying is straightforward.
That leaves me with Amazon who took money from my credit card a few years back so never bought from them since. I did manage to get the money back after a few phone calls. Most ebay buying goes very well.
