Gratz on the acceptance!
I have become obsessed with coupons! Now I never make any purchases unless I have some sort if coupon, coupon code, or at least some sort of sale. I have coupon apps on my phone, and I sign up online for various websites so I get emailed coupons. The best ones are for groceries and everyday items. There's so many deals out there to be used. I never realized it until I seriously was on my own financially.
But overbuying can be hard to resist when you have coupons. Just buy only what you really need and use.
I cancelled my credit cards with too high interest rates and fees. I consolidated to only a few cards that give me the most useful rewards--cash rewards/money back, frequent flyer miles since I have to travel, etc.
And of course I do things like: don't eat out as often, eat at home as much as possible, no more trips to nail salon, do my own nails, stopped dying my hair because salon trips are expensive, etc.
Recently I had a broken dishwasher and I was ready to call a repairman who charges $99 minimum but then I decided to spend the afternoon fixing it myself and voila!
