Is this Britain's Most Elusive Nail Polish?

A couple of weeks ago I received a promotional email from Barry M, as I'm sure many of you guys did. And, it was advertising their new range of Nail Polishes, including the very interesting "Instant Nails Effect" polish, which you apparently paint over a base colour and as it sets, sets into a funky looking pattern (I'm still in awe over that video!!)

So, as you can imagine, I was incredibly excited to try this new polish out, and I desperately want to know how the heck it works. But, after visiting several branches of Boots and Superdrug in my daily travels, I've come to the conclusion that this has got to be the most elusive nail polish in Britain!

Everywhere I have looked, the polish has been sold out, and none of the shops I've visited seem to be very quick at re-stocking the empty spaces...either that, or the minute they're re-stocked they're emptied again!

The reason that I find this interesting, is because struggling to find a product is something more frequented by the larger price ranges of cosmetics from Urban Decay to NARS. Barry M, is instead a lower budget cosmetic range aimed at High street shops, so it's interesting to see how big an impact this brand has.

Even more interesting, is the fact that this is actually the second time in the past few months that I have had trouble finding a nail polish. Last time it was Rimmel's Matte Top Coat, which following rave reviews from other fellow beauty bloggers appeared to have been snapped up everywhere I went as well. I eventually found it of course!

But, doesn't it just frustrating when you really want to give something a try, especially when you have heard so much about it, and yet you just can not find it anywhere?

Has anyone else experienced trouble trying to find a must-have product? What lengths have you ever gone to, to get it?
