I've recently discovered some great drugstore lipsticks from Covergirl.
I have 4 shades, Romance, Rapture, Entwined and Divine
Romance is a great neutral everyday shade, while the other 3 are a bit more fun, and something I would tend to wear out on the weekend.
The lasting power of these lipsticks is great. I've worn these a few times now, and they last through meals. Throughout the day, they do fade slightly, but leave your lips looking like you've applied a lip stain instead of looking like your lipstick has worn off.
As with all drug store products, price can vary widely between stores. I have seen these are Shoppers Drug Mart for $9.99, I got mine at London Drugs on sale for $5.99! If you decide to try these out, watch for the right price.
I will probably pick up some more of the brighter shades for spring. I currently have my eye on Temptress and Flame.
