Sands - I got the phone from Aldi's, I can't remember the make I'm sure it's the brand that they normally sell in there called Medion?
I'd previously bought a Binatone twin set from Eroski and arrived at house about a year later to find phone line dead. Eventually fixed by Telefonica but the fault had killed the base station.
We'd just changed over our house phone in UK from Binatone so we had a spare base which my husband brought over with him.
On the base stations there are two leads, one's a power lead which has a female/male connector point at the other end, the other's the lead which connects into the telefonica point. This lead has a telephone connector at each end, I'm sure the cheap phone I originally bought both connectors were identical. The Binatone from Eroski was a universal make so the telephone lead had an English connection at one end and a Spanish connection at the other. English BT points are fractionally bigger.
I knew then that I could buy an answer phone here as long as it had the same lead system. Unfortunately when I set it up in Spain I was unable to use the Binatone power lead in the new phone as the connection was different hence the need for the English to Spanish connector.
So unless the phone you buy in Spain is a universal then you're still going to have a problem. I'm sure I read that someone was able to get an adaptor from Telefonica for his laptop, perhaps they sell the connection leads.
Ovens Cooking in ovens is an English thing, a builder told someone on another forum that his wife had never used hers since it was installed and did all her cooking on the hob. I only had one shelf in mine plus two shallow trays which fitted into the side runners. I bought a couple of adjustable shelves from Kleeneezy and took them over on the last trip.
I think also a lot of people use those tiny oven/grills, the ones that are smaller than a microwave.
As to the cuts of meat in Mercadonna perhaps it's done that way for quickness, doesn't take that long to cook? How much meat do Spanish people eat?
Whenever we are over we eat mainly fish as we love to try the different varieties and chicken. Did get a book from the English bookshop explaining the types of meat and fish available. Handy when you want a particular cut of meat from the butcher.
