I’ll have to check this out at some point also, I just use BrickLink and spend a lot of time sorting through stores.
>> Does it take into account that some places have fees? … and that shipping from Canada costs a lot more than shipping from New York?
This isn’t surprising, but it also costs more to ship from Canada than from Germany (which actually I see Greg already mentioned), I stopped looking at Canadian stores a long time. BL lets you search by USA stores only, but it still doesn’t account for variations inside the country, it costs a lot more to ship to here from Oregon than from Ohio and I’ve run into problems with that.
I also have not figured out how the European VAT thing works and if I need to worry about it when ordering from over there.
