Earned $5.00 and Donated a Tree Today I earned $5.00 in Amazon gift cards from Perk TV. Sign up for Perk by clicking the screenshot above. Today I donated a tree through Treecycler using some of my Swagbucks. Each tree costs 99 SB’s, which is about $1.12. For each $10.00 I earn on Swagbucks, I donate one tree.
