AEON Wellness

AEON Wellness is a drugstore located inside AEON Big department store on the lower ground level of Mid Valley Megamall. AEON Big is a discount store similar to a Walmart Supercenter offering all kinds of goods at low prices.
AEON Wellness is similar to other drugstores like Watsons and Guardian in regards to what they offer. They do have the usual product items that you would find at a CVS, Rite Aid or Walgreens in the US. Though they also carry Asian medicinal products as well.
The prices here are a bit better compared with the other Malaysian chains. Stocked up on items like Ho Yan Hor, one of my favorite Chinese herbal teas and white flower oil as they cost significantly more if I bought them in Seattle. For the tea, the price is about half compared to what it costs in Seattle for instance.
As I mentioned in my Watsons review, I would recommend bringing sunscreen and insect repellent with Deet from home rather than buying them in Malaysia. I found the selection for these products to be lacking. I only found one sunscreen product here and the price was more than you would pay in the US. Other than those two things, you should be able to find any items that you forgot to bring from home at AEON Wellness.
If you are looking for the best prices on drugstore items, I would recommend shopping at AEON Wellness. Though the store tends to attracts crowds. As long you are fine with dealing with more people shopping in the store as this is part of AEON Big, this drugstore will serve you fine.
