Resellers Reality

Is anyone else noticing the trend of thrift stores catching on to the resellers world and pricing items at max retail? Seems like this time last year I could buy shoes and clothes by flat price at Goodwill, Salvation Army, etc. Now all thrifts pull brands aside and price them at max retail resell (i.e. 1/3 of new retail) squeezing resellers like myself out. It's depressing 😞
