It's a shame that nothing is listed, it would be good to look to see if there could be something there we could help you with.
I don't really know the markets for those products well, but from my perception I wouldn't consider them to be Hot Sellers. The Oakley sunglasses, well ok, there has to be a market there, but how long did the listings last for?
When selling on these types of platforms you can never judge the success of a product based over a week of marketing because you never have the same buyers in the room in any given week throughout the year.
I suggest test marketing any product over a period of between 3-6 months minimum, but the longer the better. That length of time then gives you more reliable data to base decisions on. Yes, there are products that you can have instant online sales success with, Apple iPhones for example, but they are always the hardest to source and the most competitive to sell.
I just get the sense that you may be expecting a little too much, a little too quickly. You did have lookers, but what a lot of online sellers never realize is that bricks and mortar stores also have lookers, not everyone is a buyer.
The problem that online sellers have with lookers is that it's a whole lot easier for people to look because they can do it from their home or office, so online sellers will always get far more lookers than actual serious buyers.
I would like to see you list another product if you could, then send us a link so we can take a look. List the same product as you did before and monitor the data that you already have gained to match the new data against.
