Ali express is great when you want to spend very little for products. They even do free shipping to New Zealand for many things. Shipping can take a while, but that free!
Some things are a little too cheap in quality, but in general, it's pretty good.
Only annoying thing is that people message you thanks for your order, your item has been shipped. Excuse me valued customer, please don't give less than 5 stars until you talk to me, don't open dispute, just message me etc etc. Try doing a good job and I will give you 5 stars!
You also automatically post feedback as anonymous, yet people message you and ask you to change it to 5 star!?!
