Whilst haggling isn't as common here as it is in the US, I do it all the time, including John Lewis, lol (department store).
There's only one LQS here, but I've asked the owner a couple of times if she'll match internet prices for items - whole roll of Bondaweb, sewing machine etc. When I bought my machine there was a special offer on several websites for a free extension table - I asked if she would match the deal - she did.
Re fabric - I buy from the US all the time, particularly eBay US. Even counting the cost of a Priority Mail envelope at $23.95 (for up to 8 or 9 yards) still works out cheaper that paying $22.50 a metre (39")! I'm waiting on a yard of particular fabric from an eBay seller - cost $6.95, shipping $8.95 is still a good deal compared with $22.50! Shop around for shipping costs. Small items won't incur duty or tax.
Can't help with the Juki - it's not a popular model here. I think there's only one LQS in Scotland that sells a couple of the models.
