My son spends way too much money on those drinks.
Yes, I do too sometimes and it’s a total ripoff. So this Sodastream really helps.
The best price at Walmart for a 4 pack of Monster is like $6. So that is roughly $3/liter. If I can make 12 liters for $1/liter, I would pay $36 for the same amount of drink buying it in bulk at Walmart.
Buying it at a convenience store is even worse, like $5-6/liter.
