ATLANTA -- What if we told you that you could save money on almost anything you buy from groceries to plane tickets just by shopping on a certain day of the week.

If you are a savvy shopper you can pay less than your neighbor every single time.

In an economy where we need to make our dollar stretch, here are the insiders tips on what days you need to shop.

Need to book that flight? Most airfare sales start on the weekend, but the sales prompt competitors to lower their prices. So by mid-week, the price wars are in full swing.

For the lowest prices book your air travel on Wednesday mornings.

Holiday shopping at the mall? Department stores mark stuff down for the Sunday circulars, but they usually start the markdowns on Saturday evenings.

The best time to shop department stores sales is Saturday evening right before closing, but as free standing clothing stores, they usually start their weekend sales early.

So for the best selection at stores like the Gap and Ann Taylor, the best deals and selection are right before closing on Thursday evenings.

Experts say the same is true for book stores. Major chains like Barnes and Noble and Boarders release their sales on Thursdays.

If you’re more of a movie buff, most theaters offer mid-week discounts, so catch a flick on Wednesday for the best price. The same is true at amusement parks.

Restaurants typically have the best selections at the best prices on Tuesday nights.

But if you want to stay home and eat, head to the grocery stores Sunday through Tuesday when you can combine the Sunday coupons with the week's sales.

Gas prices are falling, but if you want to get the very best price industry experts say get gas Thursday mornings before 10 am when gas demand is low and before station change the prices. You will get the best deal.

The same game works for big ticket items like cars. Dealers love the weekend foot traffic, but when things really die down and dealers really want to make a sale, Monday may be your best time to get a good deal on a car.

Before you book your next hotel room, experts say you can negotiate with managers. Call the hotel directly on a Sunday when the non-revenue manager is on duty. They may be more likely to make deal.
