I believe Stila was in some serious financial troubles last year, they were then purchased by another company. The impact was that they have virtually pulled out of the UK market altogether. Debenham's are discontinuing the line, they have some Stila items for sale online still, but once they're gone, they're gone. Personally I think your best bet would be to purchase Stila from the US using a parcel forwarding service, the range will be better than what you'll find here, and if you order enough then the postage should pay for itself. Sephora etc have a lot of value sets that would probably make it worthwhile.
