I think if you were to do this right...
List all the pro`s and cons and the level where you need to be compared to your competitors - and the cost`s that is left unsaid like inventory.
If there is a easy way to remove your inventory without trouble then you are in the green.
this is a good advice, good plan is better than having a good items to sell. I would have done the same too, study the field of items you want to sell, most probably it would be better if it is your field of interest since you already know what makes people like you interested. Then study the price and look for cheaper sources of the item so you can put an additional or better discount than your competitor.
for me online shop there are thousands of websites to go shopping on Internet many with thousands more independent sellers the majority of these are perfectly legitimate but spotting the fraudulent ones takes a bit of research if youre using a website youve not used before search of them online to see if they have any negative feedback for independent sellers on a website you can check out their online reviews on a site if you're buying an expensive item check the manufacturer website to make sure you're using an authorized distributor or seller.
