Yeah, I think the version on Cowboylyrics was posted by Gene above. I like the idea of posting various versions - and of telling where they came from.
Here's the URL for Cowboylyrics: http://www.cowboylyrics.com/tabs/misc/saving-up-coupons-3337.html - I won't make it into a link because of the popups. It IS the same as Gene's post, even to the spelling of "sevnteen thousand."

If it's an old, interesting song at cowboylyrics or cowpie, you can figure it may have been posted by Gene - and that he may also have posted it here.
