Times are indeed getting tougher: inflation, customs barriers, shipping costs, etc.
Nothing to do with the situation fifteen years ago, for example.
As far as I'm concerned, I have to add the lack of space, as I like my collection not to be in boxes.
As I collect in almost every direction, I'm forced to make choices and pass up a lot of things I would have bought before.
I don't think I'm an isolated case, and I'm not the worst off.
