Make a List — and Stick to It
This isn’t really top-secret information, but running into Costco for “just a few things” can easily turn into a multi-cart shopping extravaganza. Save money at Costco by practicing a little discipline and doing your research.
“I routinely save $100 or more each visit when I shop at Costco,” said Thomas Miller of Keller Williams Capital Properties. “I attribute my ability to do this because I am very selective on what I purchase, making sure to only purchase the items that I know offer the most savings.” Make a list to keep your spending under control and on track.
