Hi Norm and Mf,
Packaging is about $1.70 for a small bag or $2 for a Parcel Box Small 220x160x70mm and packaging is sometimes half if you buy in a 100 lot.
I know a lot of shops sell items for $25. that pay $1. for the item landed in Australia.
Tube 50 cents ,packaging $1. ,$5.50 post , cost is $7. , profit is $2.90
I bought some gasket sealer High-Temp RTV Silicone in a 3 OZ tube for $15. on eBay delivered, the postage price in
Australia was $10. , so the Silicone is $5. , If I go to a cheap shop here the Silicone is $26.
The Silicone I bought was made in Mexico so you would think the silicone costs about $1. landed in Aus, so $4. profit.
Not much profit from each item but adds up when you are selling box loads of items.
Another possibility is people are selling free samples that factories give to businesses to try ,a lot of places send
free samples before you make an order when buying in bulk . There are always people selling factory seconds online but don't tell you.
Factory seconds they can get from the bins and then there are all the items that just disappear from manufacturing and shipping
containers.
Cheers
Max.
