@green I see. That is not something we offer at the moment but we will definitely take your feedback into consideration for future feature enhancements. Is this something that you think everyone would want? Is it something our team can help with in regards to them not following our Community Guidelines, Posting Rules, or Item Guidelines? I know you explain a little bit, but more examples would help. Let me know.
The same problem occurs on other Ecommerce sites as well. Ebay & Etsy do not offer that feature, but do have filters for price, location, used/new, etc. Sometimes it is all about key words in a search to whittle it down. I am sure OfferUp will tweak and adjust as time goes by, adding features and options as they go? They need the feedback and suggestions from users to fine tune things. Some are realistic, some are not. There is NO PERFECT venue or platform to sell from. Some are better than others. You pick and choose which one works for you. Such is life on the internet. I wish you all good commerce!
