I haven't yet done any business with Amy Wan/ Shenzen Luyuan, but they are widely touted by a lot of other members here in terms of how well they pack their cells and how they do business. If for some reason everything goes to crap, they have historically speaking been good about resolving issues. And if they don't, that's an advantage to paying with Paypal, as you can open a dispute through paypal about it if theres problems that you can't resolve.
I don't know how it works in Au, but in the USA if you pay with a credit card, you are also able to open a dispute case with your credit card even if for some reason Paypal didn't find in your favor.
If you're not familiar with how Paypal settles disputes, look into it a bit. It's not exactly "no question asked." In an 'item not as described' case they will ask you to present some evidence before they issue a refund. This might involve providing photos of the product, showing communication between you and the seller where the seller advertises the product as excellent, new condition etc etc.
If the items never arrive, then Paypal in my experience, usually processes the 'item not received' cases much more quickly and easily. Essentially, if the seller can't show proof of delivery, they quickly process a refund.
Either way, it could take a couple of weeks to resolve though.
"DAP" is delivered at place, if you do a quick google search, you'll get more info than I can type here. But the short version is that you may be responsible for certain taxes or fees once it is delivered. Most small scale buyers like to pay to have shipments priced out "DDP" or Delivered Duty Paid, meaning that the buyer doesn't pay anything other than the agreed price to the seller; the seller covers import/export duties, customs fees etc if they're applicable.
Again, I'm not Australian, so I can't comment as to what you should or should not expect in terms of those fees, but that's why a lot of people prefer receiving shipments DDP-- it's just easier and simpler for the buyer.
so about a mere 3 years ago buying batteries from China was literally the Wild West .... allot of these ppl didn't even know what Grade A was but they had a sexy website (which in China takes about 30 seconds) and swore the had tons of them at a great price -- ppl bought the hype only to find out that your Grade A was some discarded battery that the manufacturers could not sell as OEM ....
also - LiFePO4 was relatively new and not allot of ppl were jumping on that band wagon
NOW things have changed ... allot
But ppl get confused on -- manufacturers vs distributors
so many times I hear ppl say they buy directly from the manufacturer to get Grade A batteries ... is that true ? YEP you get fresh off the rack Grade A's -- but usually at a higher price....
Manufacturers sell the battery directly to you. They make it, they ship it. NO discounts - you pay exactly what that battery costs TODAY.
Distributors on the other hand buy like 10,000 GRADE A's at a time .. they get a great deal and a much lower price. They do not have to take possession of the batteries at once - they can basically put them on "layaway" and get them when they need them ... so the REPUTABLE wholesalers save 30% buying it in advance and pass a 15% savings on to you (im just using the figures as an example) ... You are still getting that fresh Grade A as the guy buying directly from the manufacturer
The only risk - and it is a risk - is that your distributors are actually buying A- and not A+ and not only getting a huge discount from the manufacturer but also ripping you off - they just hope you don't notice ... and often times most don't ... Grade A- can mean things like 270Ah instead of 280Ah ... or a little puffing or the QR code is missing etc etc ... so the distributors buying GRADE A- are making allot more profit then thosr buying A+ and selling them to you ....
Have I got Grade A- batteries that work great - YEP ... but I made it painful for the seller and asked Alibaba to step in and get some of my money back ... weird formula they use which i can go into at another time ...
Also there are (3) things that they know protects YOU and screws them -- your credit card company, PAYPAL. and Alibaba... You get a battery - its not right (won't go through the long list) .. you contact battery manufacturer ... they blow you off or give you the run around ... I immediately tell them that I am going to my CC company -- NOT PayPal -- NOT Alibaba .. but my CCC ... they usually change their tone right then and there
what happens when you go directly to your CCC is that instantly PayPal and Alibaba is charged with a payback and an investigation by the CCC is open. NOW you must pay close attention to this. Many times the Battery ppl will send gobble-goop to your CCC and if you don't rebut this then you loose --
Also - the battery company does NOT get their money from Alibaba - even if everything goes great until the "quality assurance" clock runs out ....
I have stopped payment on several things with my CCC .. they tell Alibaba ... the vendor makes it right ... I say its fine now ... and it still takes the vendor now 30-45 days for Alibaba to release that money
I say all of that rambling above to say -- its different NOW.
Consumers and sellers have got smarter ...
Yes there are still people selling B's for A's but they are just rolling the dice hoping you don't notice ....
Been to China many times for work since becoming US Citizen ... if you could go to the Battery section (literally) of China and see that it is literally hundreds of thousands of batteries a day going out you would be amazed.
I guess the trick though is to not be the first person to use someone ... I often am but I explain to them directly that there is no wrath greater than an bored angry Chinese girl in the middle of a 105 degree desert with time on her hands and a credit card issued by a company that will find a hole and bury them if they screw me ...
And have I got screwed after making those threats - YEP -- but I have NOT made it easy for them ...
But prices change daily on Alibaba.... talk to the vendor -- You are the buyer - ask questions of the sellers -- sure most will push the truth limit BUT then come here and ask --
sorry for the rambling -- just trying to find a reason not to go out to the generator site on a now 109 degree day ..... aaggghhh
