Salam,
i suggest dat the nearest person to ur wife is U by urself... so try to find out wat she likes the most. Sumthing dat will make her happy with a BIG smile on her face.
Perfume? books? flowers? jewelry? movie? any collectible? shoes? bags? clothes? dinner set? kitchen stuff? or INSTANT CASH hahahaha..... i would love that option if my husband will give me his credit card to shop for anything i want hahaha just kidding.

Wish her HAPPY BIRTHDAY on my behalf : >
