Okay thanks for the replies. I really had no reason to expect deception, it's just that I haven't made a custom order like this through Aliexpress before, and I haven't dropped this much money all at once on Aliexpress before either. So I was just being extra cautious.

Barrier is also the wrong word and makes it sound like I'm having a tough time communicating but really it's just that I have to put a little more time and thought into reading some of the responses, and I also try to use more direct and specific wording than I normally would.

Ultimately now the order is complete and I eagerly await the delivery!
