New offers typically show up on Sundays, Thursdays, and the first day of the month, however offers can appear any day. In addition, every Tuesday is a "fresh savings" offer for some fresh produce.
You select offers and add them to your "list."
On the list, you can see all your selected offers and expiration dates.
There are two kinds of offers. The first is simply a dollar amount back when you buy a particular product (Ex: $1.50 when you buy Excedrin 80 count). The other is known as "one or many" offers. For these, you can buy multiple of an item to reach a threshold. (Ex: $4 back when you spend $15 on Beech-nut). Often the "one or many" offers have the ability to "boost" or complete a task to get credit towards your final dollar amount.
Some stores require you to link your loyalty card to get cash back. When you do this, the system should automatically give you credit for qualifying purchases; this can take 2-14 days. If your store does not require you to link your card, you can simply redeem by scanning the product and then uploading your receipt to the app.
Once you have received $5 in earnings, you can cash out into PayPal, directly into a bank account, or even redeem for gift cards.
*Tip: I always add offers right away if I think there is a chance I might use them. Sometimes an offer can show as available, but when you go to add it to your list, it wont let you because the max # of people have already added it to their list!
