Fresh Direct is an online supermarket that will deliver food directly to your door. In general, you are paying a high premium for convenience so my family has never actually used their services before.
That being said, right now there is an opportunity to save 53.33% off Fresh Direct with an American Express card.
Here's how to do it:
1) Log in to your American Express online account and check out the "Offers For You" section to see if you are eligible for $30 off a $100 purchase from Fresh Direct.
2) Use coupon code DM2FK8 for $50 of a $125 purchase for new customers. The price will drop to under $100 unless you spend $150 so you won't be able to combine the two offers unless you spend $150 before the promo code.
Your final price will be $70 for $150 of Fresh Direct or a savings of $80 which is 53.33% off!
Before you order make sure it is cheaper than your local supermarket, but I imagine it will be.
