I used to see great sales on GL, with aggressive growth. Then they renamed themselves, redesigned the site, and most importantly, changed their whole pricing structure to be more competitive, which resulted in much lower commissions for me. I raised my pricing to compensate, but that may have just ended up pushing buyers to my lower priced competition. I had been tracking at 2x year-ago levels, then after the change, I'm well below where my earnings were last year.
I still like the site and the owners, and uploading is the easiest of all the agencies, so I'll stick with them and hope they see some growth.
