In my first month working on couponing, I've learned a lot of things that I never realized about how coupons can be used to save money. Here are some basic tricks that everyone should know when you're using coupons.
Buy One Get One Free Sales:
An item on sale as buy one get one free in the store can have a buy one get one free manufacturers coupon applied so that both items are free.
If an item is buy one get one free, you can still use a coupon for each item. So if you have a $1 off coupon, you can use two to get $2 off the bought item.
On most items, you can use one store coupon and one manufacturers coupon, potentially stacking them.
Check to see if your store allows you to double coupons. Some stores will double or triple up to the value of a dollar.
Looking for Overage:
Keep an eye out for items that you don't necessarily need, but that you have coupons for over the value of a product. This happens most commonly when medicinal items go on sale. The overage can be used to cover other portions of your bill.
