I say cool because it’s services are too good because of its prime delivery since prime service is free for one month.It has so many amazing brands so you can buy everything that u went easily without any problem, and also when you order with your mobile phon’s app. if can not like to buy anything you can return easily so, I think now you can understand their service and I suggest you to never return their product because their product are too good. it also deliver their product one time
