To decide is the most difficult

For how many days now have I been surfing the webb trying to find the best yarnstore but yet not reached my goal? I am just saying - how difficult can it be? Really difficult it seems. I am not finished yet. And it seems as if I start all over every time I do this. Shall I buy the yarns from US or from England? What would be cheaper? And which yarn store has the wider range of yarns? I would like to buy a lot, as the prices often are much cheaper than in Sweden.
