1. Use Manufacturer's Coupons

Walmart's prices are already rock-bottom, but shoppers can combine those prices with manufacturers coupons to get them even lower.

2. Price-Matching

They'll price match any competitor. Just bring in the ad to get an item for the price -- even after it's purchased, its not too late. The Savings Catcher app lets shoppers scan the barcode on the receipt if anything they bought was cheaper at any store in the area, and the customer automatically receive a gift card for the amount.

3. Get The Walmart Credit Card

The Walmart credit card has no annual fee, but it's got plenty of perks, including $25 back on the first $75 spent, plus five cents off of every gallon of gas bought at participating stations.

4. Sign Up For The Newsletter

Walmart's newsletter sends customers exclusive savings and lets them know about sales before they happen.

5. Free Shipping

The site offers free shipping on orders over $35.
