Don't be too hasty - Are the varieties of these bottles pretty common/still in production? If no, this could be a good thing. You can still make a no bad wee profit if you shop around for limited edition or more-so, small batch whiskies. The 'limited edition' bottles are a tricky market though. Just because it's 'limited edition' doesn't guarantee its value will increase with age.
However, small batch whiskies are worth keeping an eye on. Following a bit of advice from my Papa, I bought a bottle of the special 1000 bottle run of MacAllan released to celebrate the wedding of William & Kate. Paid £200 for it in 2011. Last time I checked, it was going for about £1500 on the whisky auction sites.
ETA: Just googled it and there's a bottle going for a little over 2K on Amazon.
