Hi Ferreted,
Have a safe journey and welcome to Malaysia! Well, if you want cheap stuff you can always try the pasar malams (night markets), there are a few near your area, i.e. SS2 on Monday, Chow Yang on Thurs, and Taman Megah and Paramount on Sunday.
Who knows, I might just bump into you - I am often at the shopping complexes near your area, i.e. 1Utama, Ikano, TheCurve hehe...
Oh, and you're just in time for the Mooncake Festival this Sunday... don't forget to grab a bite on some mooncakes hehe!
