We had a similar issue with the Vulcan to the Sky Club magazine ring binders - needed to buy in bulk for a sensible unit price, but a very slow seller that took up loads of space! Of course, as soon as we sold out (after about 8 years), a few people wanted them!
Personally, I wouldn't buy any - I keep the odd Courier of particular interest and then recycle the rest as the DVD versions come out.
