I have sold guitars both here and on eBay, and it is a very anxious time while you wait for safe delivery to the buyer. Loads of bubble wrap, strategically placed cardboard stiffeners, shipping boxes blagged from guitar shops, insurance (Parcelforce's weasel-words prevent you covering musical instruments to their full value so I use drop-off services via Interparcel), and it could [i]still[/i] go t!ts-up.
So... I do have sympathy for collection-only sellers. Considering I now have to travel at least 40-50 miles to find a decent guitar or bass shop, going to see something 100 miles away is not such a hardship. However, Scotland is out of the question, and Wigan should definitely be avoided.
