We stayed at the cap de mar last year in Cala Bona last year, and we found out that the pampers nappies in the small supermarkets are every expensive.
We found a large supermarket in Cala Millor which is just up the road, be could not find any pampers there! and the nappies that we purchased were useless.
My advise is for you to take enough nappies from home to cover you for the whole holiday
