Phillips Hue Kit and Bulbs

I'm looking at buying a Phillips Hue starter kit and getting some additional bulbs.

I have one Xiaomi Yeelight WiFi RGB bulb which I installed in my bed light, I used the colours a couple of times just for fun, but since then it just stays on the one colour (a warmer white). So I don't think I need to worry about getting the colour Hue bulbs (especially for the bedroom), just the white bulbs which you can set the colour temperature.

My question is, where is the best deal on a Phillips Hue White Starter Kit? And also additional bulbs?

I have switched back to iPhone and my wife uses an iPhone, and most of our devices are Apple so I'd like to setup HomeKit hence the Phillips Hue vs more much cheaper Xiaomi Yeelights…
