Just realized that the coupon for the $8 SoftMaker Office 2018 Standard packages (Windows, Mac and Linux) appear to be generic and (apparently) it's an open-ended sale. If you see a slot for a coupon, just type in "extralow" (without the quotes). I don't think this sale is connected to any user name or customer number. There's also a CAD program for $20.00 and some font packages for $1, $2 and $4. (Specialized fonts, stuff I'm not really interested in.) At any rate, I think this link should work for anyone.
