Being cheapest off all, Amazon provides a good platform for buyers. I say good because certain aspects needs to be improve. For example, the subsections can become confusing at times. Its like too many cooks spoil the broth; too many subsections tend to make it more confusing and sometimes the products searched for, when searched in the subsections, suddenly changes. I mean if youre looking for item A and go deep into the subsection, it might suddenly show you item B which is remotely related to item A and you most probably dont even need it.
The user interface is normal, alike to other online shopping sites/apps.
Overall, as a buyer, I would recommend Amazon any day over other sites.
