Ah! The Seventh Cavalry - just in the nick of time!
Seriously, I think the moral here, as should be applied to any model shop, is to ring in advance of ordering or travelling to make sure that your intended purchase is in stock. If you're in the area anyway or just going to have a browse round then there's much less scope for complaint - just be careful where you tread.....
The problem with this particular shop is the degree to which their service and stock levels are perceived to have fallen i.e. when you've been so much better than the rest for so long it's a helluva long fall from grace when it eventually comes. As I said earlier, it's a shame.
Just as an addendum, I hope most folk by now will have heard that Graupner were taken over around two years ago by the Korean company which makes their "Graupner HOTT" radio sets. According to one trade insider the new owners haven't much of a clue about how to run a model wholesale and manufacturing business, with the result that most of the boat kits and accessories have been discontinued. Some retailers have been quick to look for alternatives and remove the unobtainable stuff from their websites, but others are still clinging on in the hope that these items will somehow be re-introduced. The smart money says there's no chance of that happening. My advice is that if you're planning on buying anything with a Graupner label then you MUST confirm that the item is actually physically in stock before you part with your money. A retailer who takes your money and then orders such an item is living in the past - the likelihood of his obtaining it is pretty remote. There's also a rumour that Robbe isn't in a very good state of health either, so much the same would seem to apply there.
