I don’t have a sodastream. I may have to get one.
Prepare to be addicted. You can buy Coke, Dr Pepper, & numerous commercial sodas bag-in-box via Amazon & others. We just buy from the provider we found on there, now. It’s fantastic having a delicious Dr Pepper instead of the bong water in cans or bottles. It’s great for just seltzer, too.
Annd the SodaStream bottles really do stay carbonated longer.
One of the best investments we ever made!
