I ordered a small electronic component from Aliexpress. A local New Zealand retailer has the part for $37 plus ~$8 for delivery. The Aliexpress price was 95 cents including delivery.
I felt guilty that, at the low price, someone, probably in China, is being exploited for the transaction to work. Then I had an interaction with a local courier company and realised it would be almost certain someone would still be exploited if I paid that NZ firm $45.
