Plus, the price of their products can definitely add up when shopping for many items at one time.
One item I do find very difficult to spend a lot of money on are lipsticks. There are my few favorites, don't get me wrong (Bobbi Brown and Chanel, to mention a couple) but since I'm a lipstick junkie, I sometimes find it best to buy cheaper lipsticks. Yes, the quality isn't always the best and they sometimes won't last as long as better quality brands but you have the option to try many more colors without breaking the bank.
Here's a fantastic Pinterest list of popular MAC lipstick colors and their dupes, which you can find in your neighborhood drugstore.
