I love using Ibotta for many stores, and especially Savingstar. Some people also use the app Shopmium, although i dont use it much, i check it for the occasional savings. Make sure you use these apps in addition to coupons to save the most! I talk about #couponing in one of my posts https://steemit.com/couponing/@sgnsteems/how-to-make-money-by-saving-money and also some saving deals i scored. Now is the best time to go shopping for back to school deals!
