Aliexpress

They are the Chinese version of Amazon. As such, they represent a huge variety of vendors. You will most likely be dealing with a particular vendor rather than Aliexpress. I've ordered several items from them and have never had a problem. However, if you do encounter an issue, there's is little that can be done about it. 

I second what John said. I've had a positive experience on 3 purchases there so far.

Ken, John's analogy is correct, however, I NO longer use them.

My first experience was positive; the item arrived timely & without issue.

I tired purchasing 3 OTHER items (3 sperate transactions  ) but weeks after payments were made, I was informed the items were not available. A refund was issued, but 9 weeks had elapsed from "payment to refund."

When this scenario repeated itself 3 times, I vowed "never again!"  Furthermore, I know 2 others with IDENTICAL experiences.  Prices appear reasonable for unique items but it's just NOT worth the aggravation. 

"Enter at your own risk."  🙄 😯 😬 

I’ve made a few (small dollar amount) purchase's from Aliexpress with positive results. 

BUT - being Amazon-like, please be wary of counterfeit items. I heard about counterfeit items on Amazon. Then friends and acquaintances were having bad experiences. with counterfeit, stale or expired items. Finally, I purchased counterfeit (non functional) insulin pen needles on Amazon. 

I’ve been purchasing on-line for over 20 years. Nowadays I pay the extra and purchase directly from manufacturers.

I agree. I also prefer to purchase directly from manufacturers. It has been a few years, since I bought anything from Amazon.

AliExpress is where I picked up my Xerox Duesenberg at a great price. My only regret is that I can’t stop all the promo emails they continue to send me for crap I’d never buy. The unsubscribe info is all in Chinese.
