I have a variety of different products that I need to get rid off, but am having a hard time selecting a place to sell them on. Some charge more and others less. What do you think which ones should I list on? Swapen.com, Ebay, Amazon, or ioffer.com? Thank You!
I think you must do a market research first. Go for a trial for few months and then decide which one will be better for you. The brands which you have mentioned are very big brands. And they have demand in the market.
Try those sites Swapen.com, Ebay, Amazon, or ioffer.com? and see what happens. If do not try you will never know. Good luck.
