Don't know about Spain but just ordered some meds off the net that originated in Mumbai and they're costing me 33% of the price charged locally.
I know I'm gonna sound like (what is perceived here as) a typical money-grabbing pharmacist here, but here goes anyway:
Do you have a medicines import licence granted by the IMB?
Do the products you're importing have product authorisations granted by the IMB?
Do you have
any form of guarantee that the medicines you're importing actually contain what the label says they contain?
Are you prepared for the fact that Customs will almost certainly confiscate your package if they realise that it contains medicines?
Did you know that China and India are well known to be the worst offending countries for the production of counterfeit medicines, and that these, when analysed, are frequently found
not to contain what they say they do?
For God's sake, internet/mail-order pharmacy is
illegal in this country for a reason, and that reason is
your safety, not the protection of pharmacists' income. I know it totally sucks that medicines are more expensive here, but importing your own from possibly dodgy sources is not the answer! (Buying it when you're on your hols in Spain would be better, at least you can have some degree of confidence in the source)
Given your user name (serotoninsid) I'm going to go out on a limb here and guess that your med is probably one of the medications that affect serotonin levels in the brain. These can have serious withdrawal effects if they are stopped too suddenly, so if you get a counterfeit pill that contains eg paracetamol, you're putting your own health at risk.
