So where are all the unwanted Christmas presents on Ebay

[Intercity]

I use eBay as a buyer, the things I look for are out of production runs, and even when finding something I have to go to the sold listings to see what sort of prices they have gone for previously (doing this usually drops 80% of items I find from my watch list), for recently stopped item or still in production items like Dapol MKIIIs I use places like rails (cheaper shipping and they do drop the VAT for international).

Example a Coach on eBay could be 25 quid and then global shipping (for each item not combined) is an extra 15+ quid, that's a really expensive HST at the end of the day.

As for ex Christmas listings wait another week until the new year settles down, many people are still on holiday and either haven't had time or access to sort through unwanted items yet
