I'm glad you're not "unsubscribing" from YLF - and doubly glad you shared this with us, because I need to do this (cut down on e-mails from retailers) too! I get way too many of these e-mails from retailers, and I really don't need them. I've tried unsubscribing from one, several times, and am still getting their e-mails, despite asking not to. Time to assign a rule for them, meaning: they go straight to junk e-mail status upon receipt.
I like Suz' idea - it all gets sent to 'junk' and you go looking in there if/when you're going shopping, to see if there are any coupons or deals at the store you're going to be shopping at.
Best wishes for your new "junk e-mail free" 2013, and more importantly - a "mortgage free" 2017 or thereabouts. It can be done!
