MSE's weekly round-up

If you're new to booking site Trip.com, you can use our code MSETRIP10 to get £10 off a digital railcard.

Railcards give you a third off the cost of most train tickets, and our code makes a one-year railcard £25 and a three-year card £70.

You can use the code on cards including the 26 to 30, Family & Friends and Senior, though be aware that the offer expires at 11.59pm on Monday 31 August.

State-owned savings provider NS&I has launched fixed savings accounts that pay up to 4.85% interest, with rates secured for one to five years.

However, be aware that some other accounts do pay more, so see our full news story for NS&I's new rates and the top alternatives.
