Hey, sorry for the delay - I've checked my email and it's actually Farmaci Tristiana that I order from in Andorra. They have loads of options - and can compound additional things if you request it. Just make sure you're ordering the right strengths as there are lots of options.
I usually use normal shipping. If I'm not home, the Royal Mail holds it - and doesn't always issue a note - so I have to collect it at the local sorting office. Royal Mail have been able to track the shipping number issued by the Spanish Postal service which the pharmacy uses.
