failsafe gifts for teenage girls - any ideas?

[runner2]

Looking for a small gift (around £10) for 17-yr-old and 18-yr-old teenage girls, daughters of a friend I'm going to visit soon. Given I don't know individual tastes, any tips before I shop?

Mac voucher?
It’s all very high end now
maybe something from Lush.

DD would not have been impressed with makeup or toiletries, a book voucher would have been far more acceptable. I'd ask your friend what they'd like

Cinema vouchers

Gift card for Costa or Starbucks.

A tenner

Definitely a Costa card or whatever coffee chain they have locally.

I came on to say Mac or Starbucks/Costa voucher....
