Comparison

Left: S$2.30, promo price, bought in Spore, 1L
Right: RM6.99 (S$2.82), promo price, bought in Msia, 1.89L

So, can u see the big diff?

Beside this, yalkut, anlene, kitchen towel, toilet rolls, rice , ayam tuna, bread, milk etc are good buy.
But there are exp items too! Like a Korean ramen, chocolate , those import items are exp!
