Have you ever noticed that when you are shopping for something online, a few days later the item you just purchased, was less expensive? Or just the opposite, more expensive? So when you should buy? Here’s the insight on a few items.

Cars - buy on Mondays. Why? Car dealers live for the weekend, which is where they make most of their sales. However on Mondays, the low foot traffic makes it seem like the weekend will never come. So because of dealer desperation, along with fewer consumers on the lot, this gives you more negotiating power.

Clothing - buy on Thursday evenings. This is the day when the stores stock their shelves and many retailers start their weekend promotions. So you will find great prices and the best selection.

Dinner Out - when? Tuesdays. Why? Because most restaurants do not receive food deliveries over the weekend. Sunday specials, cleaning out everything, making room for the fresh stuff. So dining out on Tuesday will give you the best odds that your getting a meal worth paying for, no matter what your price point is.

Gas - best to buy on Thursday mornings before 10 a.m. Why? The price of oil isn’t the only factor the influences costs at your local pump. Travelers play a major role. Weekend demand is high, so the prices usually upswing on Thursdays as travelers fuel up to head out the next day. So if you get to the pump before 10 a.m., (that is when many station owners change their prices), you will beat the rush and the price jump.
