I'm ridiculously over-excited about this review. Apologies in advance for gushing.

All too rarely, an email pops into my inbox offering me something for nothing. This week, it was a discount code for a company I'd never heard of before called graze.com.

I LOVE the premise behind this clever little outfit. For just £2.99 a week you can get a nutritionally balanced box of healthy deliciousness delivered to your desk and personalised to your own fine tastes.

First, you choose the type of box (graze nibble or graze fruit, each with four punnets of healthy treats), which day of the week and how frequently you'd like it delivered. Next you browse the taste-tastic virtual aisles of the Graze online store to give them an idea of which natural foods you love and which you loathe. Then they'll hand-pick a box based on your preferences and deliver it to your door with free first class delivery. Genius!

The menu is a mouth-watering array of healthy, natural food; everything from fresh fruit, nuts and seeds to  dried fruits, natural treats and the best olives I’ve ever sampled. There's plenty on offer for the chocaholics among us, too. The 'eldorado' mix of cranberries, hazelnuts and dark chocolate-coated cocoa beans is  quite literally a little bit of a heaven in a box. And all items are free from artificial colourings, flavourings and preservatives .

I signed up for a free trial which involved my first box being free, and 50% off the second box. I vowed to cancel my account after that, since it doesn't really pay to write these reviews if you end up spending everything you earn on every product or service you write about.... but I'm hooked. My husband and I LOVE our little box of nutritional deliciousness too much to do without it now. We get ours delivered on a Wednesday night which is officially date night in our house, and in two short weeks it has become something of a wind-down ritual to uncork the wine and crack open the Graze box while we make dinner. I look forward to opening the Graze box with an almost irrational sense of excitement; not knowing what you're going to get to eat is bizarrely good fun, and we've discovered foods which we love but didn't know existed before. Green raisins, anyone? Or how about ones infused with pineapple juice? Awesome.

There’s no nasty upfront financial commitment or lifetime contract. You only pay per box and they only charge you on the day they send the box. You can cancel your weekly deliveries at any time and if you’re going out of town you can add a ‘delivery holiday’ for a week or two, or change your delivery day from one week to the next.

According to the Graze nutritional team, ‘grazing’ on natural foods throughout the day instead of fixed meal times provides slow release all-day energy, making it a great way to lose weight by controlling your blood sugar. All day grazing is also a good way of getting more balance and variety into your diet, helping you eat plenty of the stuff that’s good for you.

I don't know about all that but I do know that if you sign up and enter the code DNLHWLZ you'll get a free box too, and we'll donate £1 to the Rainforest Alliance in your honour! And of course no obligation to pay for any further boxes after that... although be warned, you might find yourself powerless to resist!

If you do sign up you can add other addresses to your account if you'd like to lavish a little graze love on a friend or colleague, and you can even buy gift vouchers for friends, who can choose when they get their boxes delivered without having to set up a weekly order. You can also order a one-off box if you feel like sending someone a quirky little thank you in the post.

This is an indulgent treat rather than a money-saving deal but I do think it represents brilliant value. The quality of the food is exceptional and £2.99 a week seems like money well spent in this case. The portions are small but perfectly formed - just enough for a day's grazing for one, or ideal as pre-dinner nibbles for two or even for sharing with friends. On that note I'm off for the ultimate Saturday morning indulgence; an episode of Grey's Anatomy with the remainder of my delicious graze box... I only hope someone saved me some of those chocolate-coated cocoa beans!
