Oh dear - shipping is definitely a consideration. Yes - think too long on something and it could not longer be available. On Pinterest, I keep a list of things I want and then if my usual retailers have a sale, or I see a coupon code, then I will review my list to see if I really want it still. That's another option - rather than pay full price, see if you can get it on discount later on - and gamble if it is still available or not. Sometimes I find that if I wait for a sale, when I take another look, I may not love it so much and not bother getting it in the end.
There were no retailers/stockists in the UK that had what you wanted? I have to admit that there are several UK magazines that I look and I am absolutely lustful of some of the goodies advertised by Euro makers/UK stockists, that I have not found in North America.
If you look on the very bottom of the page, above the quick reply screen (if you have it), there should be another blue bar which has a "Jump to" option to go to another board. There are two tabs on the left top edge of it, one should say "move topic", the other says "link to calendar". If you click the "move topic" tab, you can move the topic you started.
Or just start a new discussion in the paper craft board
