Go easy on me, this is my first time posting a deal. :-D
Amazon now has the factory refurbished Brother MFC-L2740DW wireless laser all-in-one for $139.36. I paid about $30 more when I got this all-in-one from Amazon back on 12/27/18. I tried to get a price adjustment from Amazon tonight but got shot down by both chat reps I chatted with. I also entered a Citi Price Rewiind request but I think it will get shot down too since the Citi Price Rewiind program excludes refurbished items (worth a shot I guess).
Staples also has this for $149.99. You might luck out and get a price match for a price for a little lower than Amazon's price.
My refurbished MFC-L2740DW came in a factory box that says "Factory Refurbished" and was packaged like a brand new unit complete with all the styrofoam, poly bagging, shipping tape, sealed OEM starter toner cartridge (good for around 700 pages) and a lifetime page count of about 185 pages (I forget the exact number) when I unboxed it.
About four years ago I got a Brother factory refurbished HL-2270DW from Staples that also came in a factory box that said "Factory Refurbished" for around $60 and sold it on Craigslist this week for $45 along with a Linkyo TN450 cartridge I got but never had to use because my HL-2270DW was still running off of the toner cartridge it shipped with (I also still had the original paperwork and software CD it shipped with).
