* It appears you get 100 points for a shelfie.
* According to the listed rewards, it takes 10,000 points for a $5 walmart gift card
* Thus, you'll need to take 100 shelfies for $5.
My assumption is that different products / stores will award different point amounts so it will probably just depend.
I was shopping at Walmart this weekend in a larger city than I'm used to, and the whole place was a mess. ( it was also in the evening. Maybe merchandising elves pop out overnight)
Not a single shelf was in order. Damaged product littering the bottom shelves, discarded items all over the store from various departments, mis-shelved items. No attempt at proper sorting of items that had only subtle differences.
It is very easy to imagine that their inventory management reports 6 of some item, but not a single one is in the place it is supposed to be.
If automatic reorder doesn't kick in until 0, then there are likely many items that will never be replenished until a full inventory is performed. (I don't even know if it is possible for a store like walmart to perform "inventory")
