Impossible to find. New old stock in original sealed retail Starbucks store box. Always kept in cold storage.
Even the box itself is in mint condition, for those looking to give one as a gift. These were among the very last batch sold by Starbucks.
A special blend they made specifically for cold brew, and as their many fans would attest- for iced coffee, nothing else compares (see online discussions/laments...). Just fill a container with cold water, add the pitcher pack and let steep in fridge for up to 24 hrs.
Each box contains 4 pitcher packs.
I have 3 boxes available, priced at $29 each. Will make a great deal if you want all 3.
Will meet appropriately at... Starbucks.
Not cheap, but a number of online posts reported the last of these offered on Amazon were quickly sold at $79.99 each. None available anywhere since.
Buy now while you can: I will also be listing these on eBay (for a higher price + shipping).
