There is an online store in Sydney (Australia) that sells the 'TB' coaches for $25.00 (about 15 pound) each. How the guy does it really has me scratching my head. A few years ago, the same coaches were costing me around $85.00 each landed in OZ. He seems legit as buyers are receiving their goods.
On the other hand, until yesterday there was also an online store in Sydney selling Hornby limited edition and Barry J Freeman limited release train sets as well as other items from the Hornby range. He had multiple items listed (greater than 10 items per listing) for each listing. Now these are supposedly limited release Hornby items. The 'Buy it Now' prices were around $150.00 cheaper than other sites and in many cases, cheaper in Aussie dollars than in English pounds on UK eBay. Suprisingly, with almost no sales over two weeks the listings vanished. Two customers received goods, but one has posted negative feedback as his Hornby DMU set did not arrive.
Cheap price does not guarantee delivery.
