In all ACTUALITY, the gas price does not vary seasonally. It varies with
the contracts they buy it on. It can go up or down at any time.

That depends on where you live and who the supplier is. Gas can and does
vary greatly in some places. Price can be fixed or varied and some even
offer options of either to choose from. When you get into large industrial
users, you may even pay for gas you did not use and the really huge users
can have prices vary a couple times during the day and metering is by the
hour.
