I use another Buying Agent myself but its not because I don't trust Jauce, its just that I starting using the other first and are use to it. Many, many members here have spent thousands of dollars using Jauce as their proxy agent in buying things from the Yahoo Auctions in Japan which are not open to the world. One thing that you must understand is...that you aren't buying anything from Jauce itself....you are only paying for their Service. The things you are buying are no different from buying from individual sellers on Ebay. They have nothing to do with the items you have bought. No warranty that the listings are correct or guarantee that they work. They can only be judged on their fees and how well they repack your items once they receive them before re-shipping to you.
There should be many other discussions about Buying Agents here at BPT's where many Members have given their help and answered questions about using Buying Agents. So go ahead...ask away...But as most all here would agree...
It will become addicting 😃
