First don't give up !!
Remember even if you only save $10.00 its $10.00 you keep in your pocket. Then if you re behind on cutting your coupons,try to go through them and take what are high value or family favorites. Sometimes a fresh start can really help. As for organization use the shoppin wizard, make sure you print your shopping list for stores you will go to regularly.
If a sale is hot don't stress your self out. Ask them when they restock and go on those days. If they are out remember to get a rain check so you can get it next time you make it to that store.I enjoy shopping late in the when my kids are in bed and the stores quiet.Or consider trading of babysitting/shopping with a friend then you can both get a great deal and enjoy some quiet when you shop.
Don't stress out if you miss a sale.There are so many sale every week just do your best.
