Right now, if you shop through Rakuten at participating merchants and spend at least $25, you can get a free NBA team T-shirt and hat, plus earn up to 15% cash back. If you already have shopping to do, this is a good portal to use~

Also, if you sign up for a Rakuten account now, you can get a $30 welcome bonus. The usual signup bonus was generally $10, so this is a pretty significant increase. If you have an AMEX Membership Rewards card, after signing up you can switch your account to earn MR points instead (all cash back converts 1:1 to MR; see the detailed introduction below). That means the $30 signup bonus can become 3000 MR.
