By order of importance (my opinion): - next day delivery even on Sunday and public holiday - customer service (return, warranty, no question asked) - same site for everything Except very rare things like appliance or foods/household or very high discount, I don't use any other platform. I know how the platform works, it rarely failed me (order or delivery or quality), find everything I need and fast. I mainly buy things sold and shipped by Amazon, less often fulfilled by Amazon (FBA).
