Is anything really free? Well, yes, some things are, but China Shipping is not one of them.
I'm going to take the Palight Boss1 as an example. I have seen it listed as cheaply as $30 USD, but that is without shipping costs. When shipping is added to that figure, it's about $25 USD more. That would put it at about $55 USD.
Ok, does that ring any bells yet? How much is the light listed for, from sellers "claiming free shipping". Somewhere from $50 to $65 USD.
So..., do I need to say more? Sure, I love to run my mouth.
They are "claiming" free shipping, but the shipping cost has been already added to the cost of the "free shipping light".
So is there really free shipping on anything? My "opinion" is NO, there isn't. Now, a seller does not necessarily make a ton of money off any one thing, but they don't hurt themselves either, or they would not be in business. Take any one of the big dealers, like DX, Tmart, GB, Banggood and others. How many products are they listing "overall in all categories", on their websites? Hundreds to Thousands of items! Just thing about the amount of products they sell. Do you think for one moment that they could offer "free shipping" unless they were already padding the "free ship" price, with the cost of shipping? Does anyone think that? I hope not.
What am I getting at here? Just remember when you see free shipping, the price of regular air shipping, plus the cost of packaging and the cost of getting the item from the mfg to the seller, along with the cost of transporting it to the seller you are buying from, is all coming out of the price you paid and I guarantee the seller is not loosing money. Why do you see so many sellers pop up all over the place? If it was not profitable, they wouldn't be doing it.
Is that a bad thing? Nope, it's a fact of life, but just treat "free shipping" as "already paid for by you" and you will start to realize just how little the actual product is worth.
Remember also, all shipping goes by weight. That is universal. A very small and light object, that weights almost nothing is much better for a seller to offer, because they can make a much higher profit. If a light weighing in at 2 ounces goes for $20USD and one weighing in at 12 ounces goes for $35USD, they did better selling the lighter one, as far as profit minus shipping.
Also, I believe that all of the "subsidies" that governments are paying to China, are just going to the Chinese government and no sellers ever see a dime of that. The government takes the loot and still charges fairly high prices for mail shipping. At least it looks that way, from looking at actual Chinese mail shipping costs that have to be paid.
Just my two cents worth and just my own opinion, based on what I read and find out here and there from anonymous sources.
