Sorry for the long delay!
We will be in Madrid on and off (Madrid is our base). Other stops include: Valencia, Alicante, Pamplona, Santiago de Compostela, Cordoba etc.

I agree with the comment that many things are cheaper here in North America. The trick is to research the item(s) you are interested in (even shoes!!) For example I know I can get a bomber-style jacket here for less then $300 CDN. It would have to be cheaper then that for me to purchase it in Spain. Any stores I can "check out" while there??
Thanks
