Day Three 9.30am: I’m out visiting clients today doing a Wimbledon promotion visiting existing customers and targeting new business. I spend £18.25 on strawberries and cream in Sainsbury’s, but claim this all back on my expenses at work.

12pm: After a lovely morning driving round visiting clients I pop to Costa and meet my boyfriend for a coffee cooler at lunch which costs me £3.35.

1pm: Pop to Morrisons as I realise I forgot to eat and pick up a pack of four Dairy Lee Dunkers on offer for £1. Have one in the car to keep me going. Fill up my car with £40.05 of petrol. All the miles I’ve done for work I can claim back on expenses – I did a total of 45 miles that I claim back at £0.40p from work, so that's £36.25.

3pm: Finally make it back to the office and sit down and have my ham salad roll I made the night before but forgot about. While I eat I have a browse on ASOS and spend £65 on two dresses for Goodwood, where I’m going at the end of July. I’m an avid shopper so paid £9.95 a few months back to get free next day delivery for a year – yippee!

6pm: I get 2 for 1 cinema tickets on Wednesdays because I got my car insurance through Compare The Market. It costs just £6.90 for two tickets! I pay, and my boyfriend spends £10.80 on our popcorn and drinks.

8.30pm: I stick a pizza on when we get in as it’s too late to cook properly. It's one that I picked up from Tesco earlier in the week on our food shop.

Daily Total: £134.55

Actual total (minus the things I’ll claim back on expenses) = £98.30

Day Four

8.30am: Am out all day today with a colleague doing more visits and drops with existing/ potential clients. We pop to Co-Op and I get a bottle of water and coffee for £2.65. She drives.

1pm: Stop off for some lunch. We go halves on some £10 chilli beef nachos, and I get a diet coke, £2.35.

4pm: Have a well-deserved cup of tea when I get back to the office. One of my colleagues recommends a teeth whitening kit, so I order the mouth guard and whitening gel for £26.99.

6pm: Get home and go for a walk with my boyfriend as it's nice weather.

7.30pm: I made jacket potatoes with cottage cheese and salad that I bought earlier in the week, and prepare my lunch for the next day: sandwiches, Dairy Lee Dunker and fruit. Then we chill out and watch Netflix.

Daily Total: £36.99
