I didn't know this popular flavor was available in September until I saw an ad in my Starbucks app. The Starbucks Twitter account announced that they received supplies last week. I could go to Starbucks and order a Pumpkin Spice Latte or I could buy a box of Starbucks Pumpkin Spice Latte instant sticks and go home.
I chose to drink the latte inside. The delicious drink was 4.95 dollars. I remember pursuing the cheaper option last year by making my own Pumpkin Spice Coffee through a recipe I found after multiple Google searches. The result did not taste as great.
I assume 7/11 and other stores will have Pumpkin Spice flavored anything soon or now. Starbucks sells Pumpkin Spice Latte till they run out of stock in January.
