I have always had problems buying something from MAC's new collections when they come out. I have found an easier way to purchase these items. Today the Retro Matte lipstick collection came out. I tried purchasing two lipsticks and an eyeshadow I've been eyeing, but I could not get it to work on my computer. Instead I turned to my phone.
Ta-da! I added both lipsticks to my cart and the eyeshadow I've wanted. It was so much faster than doing it on the computer. I added both the lipstick that I wanted on the computer, but the website would not load the eyeshadows or the cart.
It workedddd! Seriously, every time a new collection comes out I am going to turn to my phone. It took me less than five minutes to order the three things I wanted on my phone. I tried again on my computer just to see how long it would take, and it took over ten minutes and it wouldn't load the eyeshadows.
Anyways, I hope this helps! :)
