Rakuten Slice is everyone’s favorite online shopping assistant. Shopping, shipping, and saving have never been easier—or more fun. Slice keeps an eye on your purchases for you—watching for price drops, tracking your packages, and alerting you to hazardous product recalls. Never enter a tracking number again! It’s all done automatically with the e-receipts in your email...that's why it's so smart!



Auto-refund is finally here! Slice shoppers can now get refunds on Price Drops automatically. Open the app, turn on auto-refund, and we’ll try to flood your bank with cash. If an item you’ve already purchased drops in price, we’ll reach out to the merchant on your behalf and request a refund. Price Drops has helped our users save hundreds of thousands of dollars, with the average price drop putting $25 back in your pocket--and it’s easier now than ever before...

Slice automatically grabs tracking numbers from your email--so you always know the status of your shipments (i.e late delivery, lost shipment, Amazon membership). Slice also sends push notifications when your packages are being shipped or when they’re out for delivery.

Slice stores your e-receipts so you don’t have to. You don’t need them now, but you may need them someday for returns, exchanges, and warranties. Your receipts will always be in your account, even if you accidentally delete the email.

“Managing my budget is fun,” said no one ever. Slice provides you with your unique spending data, so you can see your purchasing trends and habits--and effortlessly manage your budget. View all your purchase data in easy-to-read charts and graphs.

What's New

Version 7.2.2

New year (almost), new Slice app -- or at least some shiny new screenshots. Check us out on the app store -- tell us we’re pretty. ;)

Improvements and fixes
In the spirit of holiday giving (and spiked eggnog), we’ve fixed things so that American Express users can now link their credit card to their Slice account. Thanks (and sorry) to the users who brought this to our attention -- you’re the real MVPs!

Why should you do this?
By linking your credit card, we’ll do all the heavy-lifting for you. If we spot a price drop for an item you’ve purchased, we’ll reach out to the merchant on your behalf and request money back. All for the cost of 25% of what we get back for you.

Think of us as guardians of your checking account -- tirelessly fighting to keep money in your wallet, because you deserve it.

Why shouldn’t you do this?
You enjoy spending 38 minutes on hold with customer service teams before haggling over price drops.

Can't live without tool.


I have been using this app for about three years. I can't remember exactly when I started using it I just know I probably can't live without it. It tells you when your package has been shipped, when it arrived, when expect it, and where it's location is. This applies to any package that you bought no matter the courier or seller. It also logs all your online bills that you pay. Just recently I noticed they have added new things. I haven't tried these things yet but if you're curious, I think you should! Definitely worth your time because in a scheme of things it will save you time.

Almost there


Great concept, very organized way to track deliveries. It tracks all of my US packages! It does have a delay as I usually get the original delivery confirmations and an hour later get them from slice. Not a deal breaker for me.

Not very accurate with overseas deliveries. It shows up but always errors on status and shipping info so no clue when they will arrive.

Last thing is the price drops. I would looove this option but seeing that this isn’t as thoroughly thought out as I’d like I'm hesitant with putting my credit card info on here. What if there’s a breach?

Progressively Becoming Unreliable

When I first downloaded this app many months ago, it was spot on. It track packages like a hawk and notifications were almost instant. However, as of lately the app has become delayed. This week it is not accurately tracking packages at all. All packages are showing in the orders category, and not being transferred to the shipment category allowing you to see how many days away and who the courier is. I have to manually go into the website and research this info, which defeats the purpose of having the app. I use to love this app and I hope it is not on the decline, but it appears to be.
