Starbucks and Amazon are reported to have held talks on lounge concept

The potential deal was seen by Amazon as another way to expand on the Amazon Go as a service concept, while Starbucks was looking at introducing a new cashier-less cafe concept that could attract a different segment of traffic. "Our plan is to launch a co-located store, where customers can enjoy handcrafted beverages at a Starbucks cafe, and/or pick up delicious grab & go food from Amazon Go, without waiting in line," reads one of the documents on the proposed partnership.

It is unclear if the AMZN-SBUX talks are still ongoing.

Starbucks is due to report earnings on October 22 and Amazon is scheduled to enter the earnings confessional on October 28.
