I could see quite a few places where valentine gifts are stacked in lots.
If your husband is b/w 25-30 years of age, i would prefer places like Villagio, Versace, Splash

If you husband is 30+ ...even then you could visit the above places, but my choices would be Some Jewelery shops like Almuftah in alsadd, or some other good jewelery shops. You could buy him some white silver bracelets or say a good chain...etc.

Anywayz, above all ...give him your love...WAT BIGGER GIFT IS THERE THAN A PURE LOVE THAT U CAN GIFT HIM?????

Advance valentine day wishes for you both....

Jeet
