Sorry I didn't post about this earlier today, but the Friday paper for the N&O has some incredible Harris Teeter coupons in it. It's not an insert, it's actually a full page ad.
There are four 50 cents off one item coupons, 4 $1 off any item $2 or more coupons, and 2 $5 off a $40 purchase coupons. You can use them all in the same transaction, but there are some restrictions. One is that you can't use the 50 cent or $1 off coupons in conjunction with manufacturer's coupons. But they can be used on sale items. So, for example, Yoplait yogurt is on sale for 50 cents each and you could use the 50 cent coupons to get them free (assuming there are any left!). The two $5 off coupons can be used in the same transaction as long as you spend at least $80 - one for each set of $40 purchases. And the $40 or $80 has to be AFTER all other discounts and coupons have been applied. Sue Stock says you can try to use these coupons first before you hand the cashier your other cpns and manufacturer's cpns to get around that, but it may not work.
Anyway, it adds up to about $16 total possible savings and the coupons are good until the end of the day Sunday. If you can find a Friday copy (ask your neighbors or hit the local 24 hr gas station), you could cash in!
