AliExpress is actually not just one seller but a site with multiple sellers like ebay or amazon. Some are more trustworthy than others so be careful and research the seller well.
Yup! I personally haven't bought from Aliexpress before, but I know people who have who have done so successfully. If you do the research and check the reviews/feedback of the seller/company, you should be pretty good to go.
Good luck!!
Like I said Emerald, there are negative feelings from lots of people, so while it is cheaper, be prepared if you disclose it.
Some people know everything, don't you know?
Collect what you love, girl!
