Thats right $650 if I recall correctly, they are selling quick and I don't know about restock so if you are on the fence go for it.
I got this:

https://www.walmart.ca/en/ip/greenwo.../6000199217361.
My yards are pretty small, I think about 2000sq.ft in total, and have a bit of navigation around trees etc, so I wanted something with a smaller deck. Also, got the extended warranty ($30) at Walmart as I expect the battery to kick the bucket on the Greenworks before 5 years.
The Costco set is good value though, I would have bought it if I had a bigger yard but couldn't justify the 50% extra cost.
