Low on funds but looking to do some retail therapy? Here are some ways I save money and make money.

Sell your unwanted clothes, shoes, and accessories on apps like Depop, Mercari, and Poshmark. These apps allow you to have your own storefront, where you manage what you sell and buy. When posting items for sale, make sure your pictures and descriptions are clear. I suggest figuring out shipping costs before hand because a few cents will save you from spending more than you need to. Don't forget, you can always negotiate prices with sellers that work for the both of you.

Shop on apps and stores with referral programs. You can start off by using someone's referral code, that way you save a certain amount of money on your first order. When you have an account on the app, you'll have your own referral code that you can share with your friends and family. Through these referral programs, everyone saves! I personally use Dote -- an app with a bunch of trendy stores that allow you to buy with one-tap. Start here and you'll get $5 off and free shipping on your first order.

Another way to save money is to search for coupon codes specific to stores you're shopping on. Most times, you can find codes on RetailMeNot.

Aside from RetailMeNot, UNiDAYS gives college students discounts on a handful of stores both in-store and online. The best part is you get a new coupon code for each store, each time you use it.

The biggest tip I can give you is to wait for sales and delay gratification.
