I searched with that name and got nothing in the UK, so my guess is that this might be the only way to be honest- it sounds as though it might have been deleted. If it's any comfort a seller who has 100% feedback with over 500 transactions must be pretty kosher! The only other thing I can think of is trawling Woollies- they often have Megabloks and sometimes put old stuff back out in the sales.
they had them in gamelys before Xmas, I got my dd one for her birthday and shes loved it. they were a tenner gamelys seems to have the stock as toymaster and fenwicks and bentals if you wouldnt mind browsing. Good Luck!
