Walmart has the Google Home + Philips Hue Ambiance Starter Kit (v3 Lights) for $269
Wally also claims $50 savings, but over all price compared to BB its $60 savings for both.
BB claims $50 savings ($30 on Home and $20 on Hue)
EDIT: There is an even better deal if you dont mind playing the gift card game where on ebay you buy a $150 best buy gift card and get a $15 bonus gift card. Thus, you pay $150 and get a total of $165 across 2 gift cards ($150 + $15). You can buy more then 1, but not sure what the limit is. Best Buy checkout will accept up to 10 gift cards.
For those wondering which is better, Echo or Home, Echo has a head start and right now works with more things, though Home is better for answering questions with google search history and is still young and growing.
