Best Buy has the Amazon Echo Show on sale for $129.99. On top of the product page that I have linked, it says save $150 when you buy two which will bring these down in theory to $54.99 each. I'm sure this must be some sort of price mistake or misprint but it might be worth a shot to chat or call. You cannot do it from the website but the offer is there in black and white.
Everything you love about Alexa, now with a screen to show you things. Save $150** when you buy two Amazon Echo Show devices below. To select more than one of the same item, update the quantity in your cart. **Markdowns taken from regular or Was prices. Items may ship separately. Excludes clearance and open-box items.
