I promise I won’t keep droning on about Ibotta, but wanted to offer one last way that I use it to great effect. Ibotta will (sporadically) offer bonuses for mobile shopping. So, I used my eBay shipping coupon and completed the purchase through the Ibotta app. My grand total for the items I purchased was $50.90 (out of pocket 90¢). I got back 1% just for shopping through the Ibotta app, and then also got a $5 bonus for completing a mobile shopping transaction.
Happy shopping and saving!
