English TVs cant receive Spanish language! Only joking - there can be technical problems I think the way around it is via a vid player but to save complications buy a new Spanish TV.
Whilst we are talking about shipping goods - many NEW properties are sold in this area (Costa Blanca) fully furnished including white goods. If they are sold unfurnished then you can buy furniture packages - one stop shopping - prices include delivery and installation.
We all have budgets to work to so shipping the UK furniture might seem like a good idea but to be honest we always recommend buying new here in Spain then all the white goods have Spanish guarantees (and the right plugs etc) and you can get them fixed easier if they go wrong. By the time you have the shipping costs, potential delays and possible breakages its worth thinking about.
