On the ShopBack app, you can play Cashback Troopers to earn gems.
For 250 gems you can get 10 entries for a lucky draw of $500 cashback.
For 100 gems you can get a 'Secret Box for a Mystery Prize', with prizes ranging from 10 cents to $50 gift cards.
Is it worth saving my gems for entries into the lucky draw? Is there any way of knowing how many other people have entered the draw too? The $500 Lucky Draw seems 'sketchy', although I know ShopBack is legitimate. I can't find other information about the lucky draw.
I'm thinking getting the secret box is a better idea, although winning $500 sounds good.
Any help would be nice.
