What you're seeing is likely just that time of year when your country stocks up on supplies according to how many months you set it to order for.

Wow nothing like making 30 purchases at one time -especially since I have my own contracts

The order strategy can be adjusted, but by default it is set to give you a number of months of reserve supply. If the supply falls below that water mark (with or without contracts) the system will buy it. Prevents shortages and manual interventions.
