> Will coinbase honor the price when order is placed ie if it shows $19700 then will it let me buy 0.1 BTC at this price?

No, neither the price at which they actually allow you to buy or sell BTC matches the price they display. They set the price for you, which is different in both operations (and on top they charge a fee). GDAX on the other hand (same company as coinbase, different service) is an actual market where you can place orders at whatever price you want, and somebody will take them if your price matches theirs.

It seems you misunderstood the point. So let me re-phrase as per what you said:

> They set the price for you

>> Will coinbase honor the price they set when order is placed ie if it is set $19700 then will it let me buy 0.1 BTC at this price?

In which case, the spread question is only about whether there is a huge spread between the display (average) price and their set price.
