I have been noticing that since things such as school is back in session for many people a lot of businesses aren’t as busy during certain times of the day. Therefore, in an effort to generate more business a lot of companies offer discounts at certain times of the day. I suppose the best example is food where a lot of restaurants discount its prices by giving you say 30% off during the non rush periods.
This can hold true for even places like the supermarket at late night where the company would slash its prices on a lot of fresh products as if they don’t sell it they will simply end up throwing away. It’s not a bad way to save money if you can adjust your schedule to take advantage of these discounts. It’s not uncommon too where during peak time or hours a company would raise its prices to take advantage of the crowd. May as well try and do what is best to help you save money.
