If that gets deleted, just know that it was worth it. My 'attitude' about boycotting Amazon is the same as that of several other posters: a company's failure to pay taxes is the government's fault, not mine, and I don't believe I can do anything about that. Some posters disagree with that and think they can do something about it, even with a Tory government. That's fine. They can go ahead and boycott. What they are not justified in doing is implying that they are better than anyone else.
Me, I'm too cynical to think a Tory government will try to force taxes out of reluctant companies that, nevertheless, provide jobs. I'm also too cynical to think a Labour or LibDem government would do it either. They've had plenty of opportunity between them and done nothing.
