Stockpiling

I have a bit of a bad habit, when I see something on special offer I tend to get the urge to buy it so that I can save some money and / or get a bargain, which a lot of the time works quite well, but sometimes leads to things like this happening...

 

That's 16 bottle of No7 Quick Dry top coat.  Even with it being one of my Top Coat Heroes 16 bottles seems a touch excessive.

 

Part of the problem is that when I get No7 vouchers I feel the need to make the most of them and so I do tend to stock up, this time around the vouchers combined with a Buy 1 Get 1 Half Price deal which meant that by using one coupon I could get 2 top coats for £6 (plus an additional 10% using my advantage card) so it seemed silly not to stock up.  £2.70 for a top coat which rivals ones 3 times the price, who could refuse?

 

This makes me feel a little better too...

 

Nine empty bottle of the same top coat, most are in the old style bottle but fear not the product is the same.  So at least I'm stockpiling something I will use, although it might take me some time to get through 16 bottles even at the rate I use it!

 

But it led me to thinking, is this something everyone does or am I alone in my obbsessive collecting of things when I see them on offer (sadly it's not just top coat I do this with), do you like to stock up when you see a good offer?
