Nope - it doesn't work. Offer free delivery, and you still only get pre-paid simple delivery as the postage option.

Another thing I've seen - on one of my listings, they've put the simple delivery cost as actually less than the amount that RM say is standard for a small parcel, so if I used that and tried to post it in a box, the Post office wouldn't accept it.

That's it. I'm done. No more eBay listings for me. Stuff 'em.
