Backpacker, I will be in Schiphol tomorrow, is it likely to be a more favourable price in Holland than the UK?
I would not bet on it, but it never hurts to look. Make sure you've done your research beforehand, and make note of the best price (including shipping) you can get on eBay.
So far I have found electronics on Schiphol very expensive, as they are normally using the RRP ex VAT as the retail price. While high-street or internet prices, including VAT, are typically lower.
But I was browsing the Schiphol website in response to your query and I now see that they're selling the GoPro Hero 2 Motorsports edition for a few euros lower than the price (including shipping) I recently paid to a UK eBay seller. But that seems to be a special discount instead of normal practice.
