If you have a CVS close by you'll want to do a little research. They have an awesome rain check policy and just like Walgreens, they have a lot of money making/free items. The ladies at KCL have done their homework and have put together a CVS 101 rundown and a some videos (these help A LOT). Click HERE to check out their CVS site. Let me know if you do any shopping there and if you learned anything new!
