Today I earned $5.00 in Amazon gift card credit from Swagbucks. Swagbucks works a lot like Perk (and vise versa). I have Swagbucks TV and another video app EntertainNow! from the same company playing on an old iPhone I had lying around. The major difference between Swagbucks and Perk is that there are earning maximums on Swagbucks and Swagbucks does not have the token system Perk does.
With Swagbucks, I usually limit myself to $5.00 Amazon gift cards because they cost 450 points, rather than the 500 most $5.00 cards on Swagbucks cost. That means each point is worth 1.11 cents. It’s not much but over a few gift cards, that difference becomes a real increase in earnings.
