Walgreens is having an awesome promotion on contact lenses.
If you buy your contact lenses in bulk (I do), you can take 20% off your total contact lens order and get FREE shipping. Just order your lenses as usual and then use code CONTACTLENS20 at checkout to receive your discounts. This is a great promotion and a great price for lenses from a reliable source.
Buying in bulk and online is a great way to save and you can still reimburse to your FSA or HSA, if applicable.
