Are there Starbucks/Costa on Guernsey?

[Rockbird]

I'm trying to think back to when I last went and I'm sure there were, but I'm trying to think of a secret Santa present for a teenage girl I don't know very well and my 14yo would love vouchers for either of these. Wouldn't be much use if there weren't any though 😀

You'd need to check that the vouchers are actually valid in Guernsey as well. Many UK offers etc. exclude the Channel Islands. It wouldn't be surprising if vouchers purchased in the UK are only valid in the UK.
