Loreal — Lash Blast Mascara (green tube)

Is there a way to get coupons to make up for terrible cosmetic products? I just bought a lash blast clump free mascara from Loreal, and although it does go on smoothly/clump free, it begins flaking off terribly in just a few hours of wearing it, despite that I haven't touched my eyes at all. I've never had a mascara flake off so obviously and so quickly as this one. Normally this happens after you've fallen asleep with makeup still on, and slept on your face to make it flake off this badly. I want to try other products but I'm so tired of spending money on products that don't work (simce the stores don't allow exchanges or returns on cosmetics).
