I use amazon a lot and overall they provide a good and reliable service, including delivery although there is some space for improvements.
Had absolutely no issues with any of my parcels, a few items had to be returned but it was at their cost and had no issues with getting my money back.
We can buy on this app its very easy to buy and a concept was good of this app.design and layout also good so we can find any products this amazon app very easy. No one is like Amazon! They are great! Good prices, good support, excellent return policy.
