It's called supply and demand. Right now there is no demand.
Gas stations here haven't seen any downward movement of any significance in the last month because no one is buying, so no new deliveries, so no change in price.
Except for 2 stations off the freeway that are 50c+ under everyone else because they're selling gas like crazy.
As soon as normality returns there will be such pent-up demand, prices will rise again.
Just hang in there.
