I cannot talk about Aliexpress because I never ordered there (seems absolutely chaotic for my taste), but rarely do I see better prices on ebay or other merchants. It happens, but it is very rare for my use case. In contrast, Amazon's customer service is superb. Let me give you an example of many years ago. I bought an external hard drive in Rakuten, and instead of being 2 TB, I received a 1.5 TB one. I called to complain, and they told me I was outside their complain window. The crazy thing was that for them, their claim window was since they shipped, and this purchase took 4 days to arrive. I was off by 2 days according to them, but totally fine if you count the time from when I received it. This is the opposite experience I have had with Amazon. They are always trying to help and fix things. Now that I live in Germany, Amazon has auto translate so I can keep purchasing things easily. Another example of going the extra length. That said, I try to purchase from other merchants, because a monopoly is never good, so I go to Saturn and MediaMarkt a lot.
