they have done it every year for at least the last 6 years. Not sure if they did it when I was still in CA. For the first few years I was mystery shopping I had a lot of trouble telling the different companies and schedulers apart.
I'd personally prefer to get more pay rather than faster pay. I can wait. I still do business the old fashioned way, keeping enough money in reserve to pay operational costs and personal bills for at least 3 months whether I get paid by my clients or not.
Several yrs. ago, I am guessing 15, there was a post on the Volition forum stating the shopper did not care how much he/she was paid, as long as it was quick. Some MSCs have a business model, I think Ipsos is one such company, that exploits people in need. I do not criticize such models, as it is the responsibility of ICs to ascertain if high work:quick low pay fits their requirements.
