Rakuten is offering 10% cash back at PetSmart, Gap and more until Wednesday

Rakuten's biggest cash-back event of the year — the Big Stack Event — is back, running now through Oct. 7. And there are some pretty legit offers you don't want to accidentally miss during early holiday sales.Right now, Rakuten is offering elevated cash-back bonuses for purchases at retailers such as PetSmart, Macy's, Gap, Nike, Sam's Club, Carter's and many more.With Rakuten, you can also earn American Express Membership Rewards points or Bilt Points instead of cash back if you want. So, instead of getting 10% cash back, you could earn 10 Amex Membership Rewards points or Bilt points per dollar spent. This can yield a significantly higher overall value if you maximize points with Amex or Bilt travel partners.Plus, while the Big Stack Event advertises 10% cash back, we've found some offers as high as 15% or 20%.Those new to Rakuten can get an even better deal right now and layer on a $50 bonus on their first $50 spent at an eligible retailer. This is higher than the normal $30 referral bonus for new users.Here's what you need to know about increased cash-back opportunities with Rakuten.Increased cash back with RakutenTo earn cash-back rewards or Membership Rewards points when shopp...
