Yes sometimes a particular size is not in stock but they normaly offer to change the springs for a small charge (if they have any in stock)
To keep the prices low they buy in containers full of Projumps and they come in mixed weights
It is very difficult to forecast what sizes are going to be ordered so sometimes they run out of a size and then you have to wait for the next container to arrive
As Bocks are such a low turnover sale item you can't expect them to order a container just to fullfill a few orders
And at the price they are selling them at there can't be much profit so we are lucky they keep selling them
This has been shown recently as several bock suppliers that charged more for the same product (or similar) have ceased trading due to lack of profits
Now I know it's a pain if you have to wait for a couple of months for your size (or pay more for a spring change) but don't moan too much as they might just get fed up and stop selling them then we would have to either pay more or not bock
And you could always buy a set of Skips instead if your in a hurry
but maybe £1000+ is a bit much
