The thing Atlassian had going for them is that we could get our non-technical people to use their stuff, understand it, and even customize it themselves to meet their needs.
This. Although personally I have never been a big fan of clunky Atlassian products and as a developer would prefer more productive tools, but getting key non-technical stakeholders use the same system as devs teams is a big win.
I just try to search and order from local UK websites or stores. These often offer comparable or even better prices (esp. books), plus good contact with the seller and very often a better quality. Amazon just being either my last resort if I cannot buy a product in a local mom and pop store. With possibility of not even receiving a genuine product I prefer to buy, especially electronics, just directly in normal shops.
