I'm the queen of shrewdness. I have always believed in cost-effective shopping. However, these products are worth the extra bucks:
I have sensitive skin and it's hard for me to find a product that my skin doesn't react to. Shiseido products work really well and they last for a year.
Prestige Lipstick is longwearing so there's no need for frequent touch-ups. I also found a perfect shade which I can use from day to night.
Fitflop sells the most comfy footwear I have ever tried. I can use them for hours without suffering from tender and sore feet. A must-have for those who love to walk. I bought my first pair 3 years ago and it hasn't shown any obvious signs of wear and tear yet. A really good investment.
