There "might" be a sale on them soon since the new ones coming out will have the Humminbird DI Sonar built in instead of the US2 Sonar.
I would not bet on it though as the others said if you can't keep up with demand you don't lower the price you raise it.
Then some of the components could be affected by the Tariff's?
I work in the A/C field and a lot of our parts just went up 25% because of them.
