There are risks of loosing your money either way.

My reaction would be to try and accommodate the sellers needs if there is no evidence of foul play.

A lot of the sellers on Aliexpress are very small, so i see it as a transaction between individuals.

Also I’m pretty sure Aliexpress has most sellers on a short lease, dictating rules.
That is not nice and yet onother reason for me to try and accommodate the sellers specific needs.
