The additional pricing research step in the online route requires serious labor-hours when compounded hundreds of times. Additionally, the sheer volume of items needing priced introduces inevitable pricing errors that cost these companies real money.
Happy to answer any questions in this area if it is of interest to you.
Including some signifier of price distribution by item condition in the returned results is extremely important and would be something people using this in thrift would want to see.
I'll be on the lookout.
Which thrift chain would most likely want this?
