Whats the biggest commercially availible jigsaw puzzle piece count?

[Meeko]

I remember years ago, there was a 1,000 piece “Gremlins” jigsaw puizzle. ((Yes, this was as I said, years ago.))

Last week, I saw Springbok puzzles at a hallmark store. This lead me to thinking:

Whats the biggest puzzle that one can buy?
