Give $20, Get $20 after "first Boost purchase". I get cashback while shopping with the kudos extension. Testing this one out to see if it stacks with other cashback extensions. The verifying process for purchases takes at least 90 days. Since May my first withdrawal was $13 bonus, with $25 pending ($20 first bonus, $5 cashback). The $5 is about 1.7% cashback based on the way its recorded on the kudos site. A nice bonus, because I already got cashback from other apps. The extension is for chromium browsers on pc and iphone Safari.
