More information on Rakuten
If you don’t have Rakuten, you can sign-up for Rakuten here. With this link, you get a $20 cashback bonus (normally $10). After signing up, you can go here to get the browser extension if you’d like to be notified whenever you can get cashback.
You need to spend $20 to get the $20 cashback, which equals 100% cashback for your first $20 in purchases.
With that extension, you can apply coupons automatically and activate the cashback instantly on websites. That means you do not even have to go through a portal on the Rakuten website.
Even if you already have a Rakuten account, they currently have a promo where cashback is doubled or more at popular stores.
