IKEA has a mover's deal where you sign up & will get $25 off a $250 purchase through an email they send after signing up. This will work even if you are not moving.
I input the minimum amount of information required (the ones with an asterisk). I did sign up for the "inspirational emails and updates" because it might be required. You may want to use a throw-away email. I got the email within about 2 minutes. Check your spam folder if you don't see it.
$25 off [ikea-usa.com]
ETA: After clicking the link above - you should see the $25 offer. If you don't, you probably won't get it.

Sorry if this is old news or a repost - I did search. I hope it helps someone.
