Some of my favorite stores for saving are: (always remember, our best savings are for us, it may or may not work for you and your family, but it doesn't hurt to collect ideas from others, right?)
Wal-Mart super center
Other things like clothes, etc...:
Much more than I can list but here are a few:
My mother helps out a lot with this stuff (so take advantage of your parents, they want to buy you stuff, LET THEM, so No to NOTHING!)
Really, about any store for clothes items, just scan the clearance sections REALLY well and often when you are there. Don't go out and waste gas driving back and forth!
Paper Products (like TP, Paper Towels, etc...):
Warehouse stores like BJS and Sam's Club is where we get the Best Products at the Best Prices in BULK because who wants to buy toilet paper every week? We get Bounty and Scott at BJs and it lasts anywhere from 3-6 months before we have to purchase again!
Unique Collectibles, Housewares, etc..:
I love EBAY, Thrift Stores, Antique Stores, and Yard Sales for the Unusal in decorating our home. NO I do not decorate the entire house this way, I mix it with full priced new items as well and this makes my home HARD for someone to copy and duplicate! Always get compliments and comments like: i love that, where did you get it? i have had people try to get some of the same things, and of course not able! So find your style, have patience and go shopping!
I have more favorite places for this and that; however, it is time for me to get ready for the day as my son is stepping on my feet, (he just woke up!)
