Creality CR-6 SE on sale for $339. Not sure how low this has been but seems lower than most places at the moment. This store has good reviews, and checks out and upgrades the printers before shipping. I have one on order, but be aware that if you want it NOW this isn’t going to be the place to buy it, as they seem to have a 1-2 week lead time at the moment, especially with the pandemic crap still going on. In my case they didn’t charge tax, which is nice
