Makeup: When to Save and When to Spend

I choose to splurge on
1) foundation - quality foundations have a luminous effect and have the power to make my skin look fresh and bright even during dull skin crisis moments (money spent RM250++, lasts about 6 -8 months)
2) lipstick - the perfect colour from quality lipsticks makes my face brighter and makes my teeth appear whiter, plus the fact that they stay on much longer. They also don't have the shiny effect that cheaper lipstick does (money spent RM90+ lasts 2 years)

For other makeup items I choose to save and shop at pharmacies like Guardian or Watson because to me the cheap price has almost the same quality as the expensive ones. Definite 'save' makeup items include:
1)mascara (maybelline) - quality similar to Benefit
2)eyebrow pen (Kate) - quality similar to Stilla
3)eyeliner (silky girl)
I rarely wear eyeshadow on a daily basis but I've read many reviews from make up experts and they recommend to splurge on a single colour eyeshadow that brings out the colour of your eyes.

As for blushers, makeup experts recommend that you save and buy pharmacy brands. Personally, I don't feel satisfied with pharmacy brands because the colour wears off too easily. I used to wear MAC blush but I stopped purchasing MAC items because of personal reasons. MAC blush is definitely long lasting and makes my face look healthy, rosy and bright. I've tried to replace my blush with good quality ones that cost RM90++ but the results are similar to pharmacy brands.

If you have any recommendations on makeup brands that sell quality blush and you find that the colour is long lasting and gives you that healthy, fresh, and rosy effect, please let me know.
