ANY 4 FOR $50
These powerful items are somewhere between a 200 and 500 gram item. (500 grams is 1.2 pounds of powder so figure at least half a pound or more on these.) They are already a steal at just $15 each but even a better deal at $12.50 each when you buy any combination of four at a time for $50.00.
You must purchase at least 4 to get the deal but you may choose additional ones for just $12.50 each after that.
