Understand that buy one get one half price is only a 25% discount
Yup, that one bears repeating.
Grocery shopping - stay focused, stick to your list - have a plan and a weekly, "What's for Dinner" list.
Allocate X for unexpected bargains - clearance, close out, reduced for quick sale.
Ask and you shall receive - be nice and chatty with those stock boys they are awesome money savers, they will steer you to the unadvertised bargains and specials.
Know basic stuff, like butter goes on sale during the holidays and that ham is always cheaper after the holidays.
Join all the savings clubs, do use coupons from the paper, online and know where the store displays their store coupons ($2,50 off store coupon on Hellman's Mayo made the large jar of Mayo cheaper than the small one, add $1.00 coupon from the paper) voila - nice savings.
Get an app that tells you which store has your favorite items on sale and compares prices on different sizes of the same product, better yet figure out how to do it in your head.
Find a shopping buddy to split those large, cheaper in bulk purchases. Storage and Price cut in half - nice:)
Be willing to try store brands - even if you love your favs, it's worth a try.
... and yes, to "we all have to start somewhere". Not everyone is fortunate enough to have been taught about smart grocery shopping or they might be new in town. Maybe they never learned to cook yet or just need some guidance on figuring out which items are the best deal.
I have been thinking about starting up a cooking class, maybe I'll incorporate shopping, that is actually how we were taught in school. They split us up in teams and the team that purchased that weeks groceries for the best price got a better grade.
(We were given next weeks shopping list-so everyone puchased the same items)
