Now I know this deal isn't going to set the world on fire, or have you leaping up and down with excitement, but you know what - I'm THAT sick and tired of reaching for a pencil on my desk, only to find out they've all vanished to goodness knows where, that I'm VERY excited about these 12 HB pencils for 87 pence (and that's their delivered price too!).

Tell me if any of this sounds familiar to you...

You've tidied your desk; all your pens have lids and are happily sitting in the pen pot, all the pencils have been sharpened and are playing nicely with the pens in the pen pot.

You have post-it pads too and are are just where you like them on your desk - in exactly the right place to be able to grab one at a moments notice when the phone rings, or when you need to make a note of something with a newly sharpened pencil.

Within two days, at the most, and because you live with other people, your pen pot now only contains one yellow colouring pencil, a pair of scissors, a CD marker (red), a biro that doesn't work and a rogue paper clip, along with a few unstapled staples which rattle around in the bottom of it.

WHERE have all the pens and pencils gone?!!!!

I bet no one has any clue do they, and they didn't take one either because they 'have their own!' Hmmm, I thought so, the same evil pencil fairy who visits my house must come to yours too!!!

The reviews for these 12 HB pencils with eraser tips are good - now for people to feel compelled to leave reviews about a set of humble pencils must tell you something about them (the pencils, not the people!), so if you want to stock up on some good quality pencils, this is a deal for you; hurrah!

I am SO buying these 100 HB pencils with eraser tips from Sainsbury's!

• You'll need to go to Sainsbury's and physically grab your pencils

I'm breaking with tradition here because, it would seem, that this is an instore offer only but I'm THAT sure I'm not alone in being sick and tired of there being no pencils when I reach for one, that I'm taking the 'risk'.

Let me describe the scenario that plays out over and over and over  in my house, and then you can let me know whether it is a universal phenomena or whether I'm completely alone in my pen and pencil pain...

So, I've tidied my desk; all my pens have lids and are happily sitting in the pen pot. I've sharpened all my pencils and they're getting on very nicely next to all the pens.

I have post-it pads too and they are just where I like them - to my right, next to the phone and in front of the fully stocked pen and pencil pot.

I am a very happy desk occupent.

Within two days, at the most, and because I live with teenagers, my pen pot is reduced to containing one blue colouring pencil, a pair of scissors, a CD marker (green), a biro that doesn't work and a rogue paper clip that rattles around in the bottom of it.

WHERE have all my pens and pencils gone?!!!!

The funny thing is, no one seems to know.  It's amazing - we must have an evil pencil fairy who comes and steals them all the moment my backside leaves the office chair *scowl*

Sainsbury's have a 'buy one get one free' offer on all stationery at the moment, so you're actually buying a pack of 50 HB pencils and getting another 50 free.

I'm breaking with tradition here because it would seem that this is an instore offer only but I'm SO sure that I'm not alone in being sick and tired of there being no pencils when I reach for one that I'm taking the 'risk'.

I think I might just buy 10 packs and land myself 1000 HB pencils - let's see how long it takes for THAT many pencils to vanish!
