Where to buy Adjustable Spanner

I know it's not helping... what are you going to do? damn you all take internet and this forum too serious. I'm not english, I'm finding kind of lost in this city. And i've been here for only a couple of weeks. I googled it first but didn't came across an answer.... i had to find out what the name of the wrench was in english...

So I came to the place I know where there is the most know how on the matter... I think that's what forums are for. Even if it seems stupid and obvious for you.

One thing I must say If it was on my country's forum, you would get help no questions ask.

Being Welsh is no excuse.
