This printer has popped up for less in the past, but those deals were quite short-lived, or in some cases they involved PM and YMMV.
This is a straightforward Amazon deal for $279.99, and Prime members may see an offer to save an additional $5.96 by choosing no-rush shipping, bringing it down to $274.03. That's the lowest price on Amazon so far in 2017. Normal selling price tends to range between $300~340.
