I haven't bought much this year on ebay and the majority of what I have bought has been presents or stuff for other people. Like many I'm not chasing that much stuff anymore due to collections or runs filling up and scaling down in the items/lines that are collected.
The Star Wars section is down 30% in items listed after the latest promotion came to an end on Sunday. Years ago these promotions came up about once every 3 months, now they come up forthnightly - another 5p listing day this Thursday. I also don't remember getting as many £10 or £5 vouchers to use on ebay/paypal checkout. All signs of a company trying to keep people interested.
With the new seller rules and the overall cost of ebay and paypal fees (you now have to offer paypal!) I think many people are put off. I haven't listed anything since the new rules came in and I'm going to see what happens - maybe a 5p listing day I would list some expensive things or a free listing day would list some items but that would be about it. Watch the number of Star Wars items go up at least 30% this Thursday.
I've done most of Star Wars collecting through US forums such as JediDefender and ToyTraderz this year and that represents are far better deal for both buyer, seller and trading items.
