Another Recession indicator?

For 2 years, I've been donating blood and receiving $65 to $80 per donation. Starting last month, I'm now only being offered $50 per donation. I doubt that we have a lower demand for blood, instead I bet more people are donating blood to meet financial constraints... hence, more supply, and lower prices.
