If you spend the full $1500 at Walgreens you will earn an extra $12 by linking your card with drop.
I currently have;
lyft, seamless, whoelfoods, walgreens and uber as my "power offers" where I earn anywhere between 8 and 16 drop point and a bonus supercharge for every 5 transactions with those merchants.
You can also make $20 as a first time uber eats user if you create the account via the Drop app. Didnt work for me using google voice or my actual phone number that I already have with uber. Looks like you need a real new number.
