You paid roughly 1/3 of the retail value- that's super! The reason they do so well is a few things- MANY hours spent planning (I'm happy to put time into it, but if I ever approach 40 hrs a week 'couponing', please hold an intervention), stores that double coupons, and a HUGE stash of coupons.
Doesn't work for me because- my 'usual' store with the best prices never, ever doubles, and I am in a very rural area, so 'store hopping' is not feasible, I do not have anyone to give me coupons, nor any recycling dumpsters to dive through (I often wonder if I would if I could- verdicts out on that one still)- so I get what comes in the paper, what I print online, or what I order through a clipping service.
I don't do too badly- usually $8-18 at the grocery store each week, plus much more at the drug stores I frequent between coupons and rewards. I have gotten back into 'ordering' my coupons from coupon clippers, helps me have multiple coupons on hand for when items we buy go on sale.
My husband, who only likes the 'plain' coffee creamer, was asking me the other day why I bought 6 big bottles of my flavored creamer in one week...well, because between the sale that week and my coupons, I got them for .50 each, instead of the usual $2.79 or so. To me it was a great find! I'll never be an 'extreme' couponer either, but I'm happy with how 'moderate' couponing is working for us. Saved $30+ at the grocer's today, paid most of the gas in my car for the week!
