People have just four days left to secure hundreds of pounds in cashback, warns Martin Lewis.
The Money Saving Expert founder said it would soon be too late to apply for the Chase banking app, which can reward customers with unlimited cash returns
In his latest newsletter he said: "For over a year now, the Chase banking app, owned by US giant JPMorgan, has been in three best-buy categories.
"And as you don't need to switch to it to get the perks, it's easy to use in conjunction with your existing bank."
If you sign up for an account, you get 1% cashback on everyday spending when using the Chase debit card.
But from next week, the amount of cashback that can be earned will be cut to a maximum of £15 a month.
Martin said: "Apply by Monday, May 8, and for the first year its debit card gives you 1% cashback on all normal spending done on it (it excludes buying cars, art, gambling and cash from Bureau de change).
"Many have earnt big, like our own MSE Steve B who earnt £402.24 in cashback since Feb last year.
"From next Tuesday, newbies get cashback limited to £15 a month (so only cashback on the first £1,500 monthly spending).
"It's still a best buy, but just not as good, especially for bigger spenders. So if you're going to get it, don't delay."
