[header] How to get coupons from walmart's savings catcher program via the walmart for iphone app [title] Enter receipts from store purchases from either walmart's smartphone apps or walmart's online site. [step] This step is critical. Per policy, you have no more than 7 days to enter the receipt for it to be deemed invalid for use. 
[substeps] Make sure that the receipts don't just have walmart-only items on them. Walmart-only items will only be found at walmart and will never be found at any other store, and thereby will never receive any returned results.
