Always Get a Raincheck!
Some stores will give you a raincheck if the product is out of stock.
For example the Arm & Hammer laundry soap was on sale for $2 at Loblaws banner stores 2 weeks ago.
But, they only had limited stock of the one type that the $1.50 coupons worked on, which made the laundry soap $.50 a jug.
A raincheck is usually good for a month so you have plenty of time to go back and get the product after the sale is over.
It’s the best way to get a supply of a certain product to stock up on for a very cheap price.
I picked up another 6 on Friday with my raincheck, and still have 1 more raincheck to use up when there is more stock.
