Atm I am making a spreadsheet of all the unused/unopened items I currently have and want to sell. However some of the items I want to sell I cannot find on the internet. I want to compare other vendor prices. I don’t know since I have had them for many years and they eventually got d-listed or these products were never sold online.
You can make a guess if you don’t find.
You can also check on Alibaba and increase price accordingly.
