I'm not suggesting you should buy any of these products at these super inflated prices, but if it's limited edition and you really, really, really want it - it could be the only way.
Chanel Platinum Duo Metallic Polish - I only talked about this product the other day, but finding it in the shops now is neigh on impossible. It's even rare on eBay with only a handful of sellers listing at almost twice the retail price - £30.
No 7 Protect and Perfect Serum - There's really no reason to pay over the odds for this product - as Boots are getting more stock in and it isn't limited edition. But if you must start working on your wrinkles now, then expect to pay up at least £30 for full size and £6 for a sample!
