If you are looking for a coupon, the best place to start is one of the coupon data bases. I like Hot Coupon World and A Full Cup.
It's frustrating to find a possible coupon, dig through your coupon stash, only to find out the coupon you're looking for, was not in the Post-Dispatch.
I've put together a list of actual coupons in the St Louis Post-Dispatch. Thanks to Sunday Coupon Preview, I'm able to start with a possible list and twink it for what was in the Post-Dispatch.

Note: I had some what different coupons in the SmartSource insert I picked up at the store and the delivered paper. I've included coupons in both of them on this list.
