I know that you cannot expect to sell Used items at the price of new items, that's obvious. I know that if you are using letgo you can get some lowball offers, but these buyers are REDICULOUS. I was checking ebaY for some going rates for used products, (computer parts.) I posted some of the same stuff on Letgo and people only want to pay like 25%-50% what you can get on other sites. The Buyers on Letgo must be high or something.
Aside from that, the whole site is tedious to use because things are organized poorly, and it's difficult to get categories of things to look at to show up in a way that makes it inviting to browse. For example, there is a category "electronics," don't you think they would have a category for say - a speaker system to segregate it from a computer monitor?
