Where To Shop
Central Shopping
There are more or less defined areas in the centre where you can shop for souvenirs, fashion and jewellry. See map here
Shopping malls
The shopping malls in Valencia are large and diverse. They can probably answer all your needs, so perhaps that is the first place to look if your budget is not too tight.
High Street Shopping
Your high street areas are Calle Jorge Juan by Mercado Colon, Calle ColonCalle don Juan Austria and the space between them. Jewelry, expensive clothes, shoes, perfumes etc.
Budget Shopping
Budget shops are hard to come by in the centre but if you look hard enough you can find the prices that suit a more remote district.
Residential areas
Outside of the centre you can, naturally, shop cheap - the more residential
the district the lower the prices, but you will be hard pressed to find
something original and/or good quailty. It will be mainly standard unimaginative
stuff. Another problem is that shops in residential areas tend to be spread
out.
Markets
You could also try the markets. Again, the cheap prices will reflect originality
and/or quailty of items. The markets are often full of stalls and stalls
selling practically identical things.
Chinese Shops
These are excellent when you don't care about quality. You can buy practically
anything, a space shuttle if you want to, and for a fraction of the usual
price. Do expect a quality disaster though. The chinese shops are spread
throughout the city. In the centre, there are a few just opposite Mercado
Central.
Wacky Shopping
For some strange and wacky shops start at Mercado Central and venture into Carmen.
