I was looking to buy the Nickel Eye Gel. It's the best in the business and normally costs £20. However ASOS are doing a deal where you get Eye Gel and Face Gel for £18. They are still selling the Eye Gel on it's own for £20!
There are probably some out there who will balk at the price, but the gel is the best and lasts AGES.
If you buy one then there is a postage charge, but I bought 5 packs (easy xmas pressies) so got free delivery.
Dunno if it will help with 'seduction' but my eyes will look less baggy all the same :)
