Thrift stores are a great way to find quality items at a much lower price than buying retail, said Janita Grift, frugal living expert and owner of Frugal Fun Finance. Additionally, she suggests using an app such as Flipp to compare the same grocery item at different stores and buy the cheapest item. “I’ve used apps to save nearly 30% on my grocery bill and stretch my limited funds until the end of the month.”
