Microsoft Edge has been working for me. Switched from Firefox which was spotty.

@mrsguin Printed the coupon twice and bought 2. Received ibotta 2 x $0.50 rebate plus $0.55 for Silk yogurt alternative

@mrvietnam you’re correct; i made another purchase and the digital coupon did not apply.

@mrsguin I bought 2 and the online $4 coupon was applied. If I bought more, as you say up to four times, will the online $4 coupon still work?
