Swagbucks is offering some users 0.5% cash back on all Amazon purchases (excluding gift cards and third-party gift cards). This can be pretty valuable for people who spend a lot on Amazon. Check your account to see whether you have this offer; you can find it under the "shop with Swagbucks" section.
What everyone can see are the cash back offers on select Amazon categories, such as Amazon devices and cash back for new Amazon Prime members, which are both pretty decent.
