Deal Details
For Costco members, the EcoFlow Delta 3 Premium (without panels) is on sale for $549 through 3/29. The most recent SDs I saw on this unit were over $600. If you don't need the 2048Wh capacity of the Delta 3 Max but want a little more than the 1024Wh of the Delta 3 Plus.

With the 220W bifacial panel, it's $849. But the panel alone is less than $300, so not sure why you would do that deal.

Specs
1.5 kWh Capacity for Backup, Outdoor Workstations, and Recreation
Charges from 0% to 80% in Just 60 Minutes
1800W AC Output with 15 Outlets for Multiple Devices
Fully Recharges in 3.5 Hours with 500W Solar Input
LFP Cells with 3000 Cycles to 70%, 10-year Lifespan, and 5-year Warranty

When I log in, I still see it available to ship but every time I have logged in for the last few days it does not show the discount price. I have been seeing it as $849. Not sure why I don't get the same price as show even though it says it is on sale.
