Survey: what price for fly food in your area?

[SandraP]

To: people who buy their fly food from a local facility

I manage a fly food production facility. As part of my budget analysis cycle I need to summarize the prevailing rates various other facilities charge for their products. What do you pay/charge for your fly food?
Is it in glass or plastic?
Bottles or vials?
How many per tray?
Is your food subsidized?

Thanks!
